Human body/Technology-Base Quora QA –Compiled
Q1 What are the most interesting and unknown facts?
A1 Anjani Kumar N, Doctor Updated 4y
Here are some interesting facts about the human body
1) Brushing your teeth too aggressively is directly related to heart disease
KR: Brushing your teeth too aggressively is not directly linked to
heart disease, but it can have indirect effects that may contribute to
overall health issues. Here are some points to consider:
Gum Damage: Brushing too hard can damage your gums, leading to gum
recession. Receding gums can expose the roots of your teeth and lead to
periodontal (gum) disease.
Periodontal Disease: Advanced gum disease has been associated with an
increased risk of heart disease. Inflammation and bacteria from the gums
can potentially enter the bloodstream and contribute to systemic
inflammation, which is a risk factor for heart disease.
Oral Hygiene: Maintaining good oral hygiene is crucial for overall health.
While aggressive brushing isn’t ideal, inadequate oral hygiene can lead to
issues that might contribute to systemic health problems.
2) VAs you breathe, most of the air is going in and out of one nostril .
Every few hours, this shifts from one nostril to the other
KR: This was told long ago by Trimular which I had written already
in thgese columns.
Nadi Shodhana, or “alternate nostril breathing,” is a simple yet powerful
technique that settles the mind, body, and emotions. You can use it to
quiet your mind before beginning a meditation practice, and it is
particularly helpful to ease racing thoughts if you are experiencing
anxiety, stress, or having trouble falling asleep.
There are several different styles of Nadi Shodhana, but they all serve the
purpose of creating balance and regulating the flow of air through your
nasal passages. In fact, the term Nadi Shodhana means “clearing the
channels of circulation.”
With just a few minutes of alternate nostril breathing, you can restore
balance and ease in the mind and body. Sometimes when we feel frazzled or
find ourselves doing too many things at once, it’s because energetically,
we are out of alignment. This breath is great for restoring that necessary
balance.
In addition to calming the mind and reversing stress, alternate nostril
breathing also:
Improves our ability to focus the mind
Supports our lungs and respiratory functions
Restores balance in the left and right hemispheres of the brain, and clears
the energetic channels
Rejuvenates the nervous system
Removes toxins
Settles stress
B) Pingala Nadi, also known as Surya Nadi (Sun Channel or Solar
Channel), is the Prana Energy Channel located at the right side of Sushumna
Nadi, and is one of the fourteen major Nadis in Yoga. It’s also one of the
three principal Nadis, that is, the trinity of Sushumna, Ida and Pingala
Nadi, the so-called Trividha Nadis.
Other names used for Pingala Nadi are Pingalika, Dumbhini, Yamina,
Yamuna, Aksara, Kalagni, Rudri, Mihira, and Candi Nadi.
Pingala Nadi represents masculine, sunny, hot, active energy, and is
the mirroring but complementary channel of Ida Nadi, the latter being the
left-side Energy Channel when compared to the position of Sushumna Nadi.
It’s generally agreed on that Pingala represents the “right breath,” that
is, breath flowing in and out of the right nostril, although some ancient
Yoga texts (even if rare) assert that Pingala embodies the left
nostril.Some assert that Pingala Nadi traverses all seven — or at least six
Chakras up to the Ajna Chakra (Third Eye Chakra) before proceeding to the
right nostril. In these versions of the presumed pathway, Pingala Nadi
doesn’t diverge to the back of the body, but rather stays at the front.
In any case, one finds several trajectories and locations described in
ancient Yoga sources, such as:
Pingala stands on the right of Susumna (Darshana Upanishad);
Pingala extends up to the right nostril (Darshana Upanishad);
Ida is on the left side and Pingala on the right side, while the Susumna is
in the middle. These three are known to be the paths of Prana (Dhyana Bindu
Upanishad);
The Nadi standing on the left of Susumna is Ida. The Nadi standing on the
right of Susumna is Pingala (Dhyana Bindu Upanishad);
Ida and Pingala conduct through the nostrils (Siddha Siddhanta Paddhati);
Pingala Nadi which is the protector on the right side (Kshurika Upanishad);
There on the left is Ida, the moon-nerve; on the right is Pingala, the
sun-nerve (Saubhagya Lakshmi Upanishad);
On the left of Susumna is situated Ida and on the right is Pingala. The
moon moves in Ida and the sun in Pingala (Shandilya Upanishad);
Pingala goes upwards to the right nostril (Shandilya Upanishad);
Ida is on the left and Pingala on the right [of Susumna] (Yoga Shikha
Upanishad);
Ida and Pingala stand on the left and the right side of Susumna
respectively (Yoga Chudamani Upanishad);
Nadis Ida and Pingala stand at the left and right of Susumna. Ida
originates from the navel and terminates at the left nostril and Pingala
with the same origin terminates at the right nostril (Tri Sikhi Brahmana
Upanishad);
There are two nerve currents, Ida and Pingala, along the spinal column and
a hollow canal, Susumna, in the middle (Hamsa Upanishad);
The right side vessel, which is Pingala, is another form of the sun, and
the giver of Nirvana (Shiva Samhita);
The Nadi called Pingala is on the right side; coiling around the central
vessel (Sushumna), it enters the left nostril (Shiva Samhita);
The Pingala also comes in the same way from the left side portion of the
Ajna lotus, and goes to the right nostril, and has been called by us the
Asi (Shiva Samhita);
Pingala is located on the right side (Goraksha Samhita);
Nadis located at the left and right are known as Tamasa and Rajasa
respectively. Ida is of the nature of moon and Pingala is of the nature of
sun (Hatha Ratnavali);
Pingala is on the right of the Sushumna and extends up to the tip of the
nose on the right side (Yoga Yajnavalkya);
Ida and Pingala are to its [Susumna] left and right. Ida is situated on the
left and Pingala on right side (Vasistha Samhita);
Pingala is occupying the right side and going upwards up to right nostril
(Vasistha Samhita );
In time by the action of Vayu a straight long Nadi called Sushumna is
produced. The mouth of the Nadi is downwards. There is a Nadi on each side
of it. That on the left is Ida and that on the right is Pingala
(Prapanchasara Tantra);
Pingala, connected with the right scrotum, encircles Sushumna, passes by
the left hip, goes to the heart-and thence passing by the right shoulder
proceeds to the left nostril (Prapanchasara Tantra);
Ida is situated on the left, Pingala on the right and Susumna in the middle
(Shiva Swarodaya);
Pingala, to Svabhavandanatha, on the right nostril (Bhavana Upanishad);
Ida and Pingala in which moon and sun continuously turn, originate from the
core of Kanda and course through left and right sides respectively of
Susumna (Hatha Tattva Kaumudi);
Hail to the left part of the forehead, Pingala, the Sakti made of Mantra
(Bhavana Upanishad).
Functions of Pingala Nadi
Pingala Nadi is said to stimulate body heat, perception, confidence,
reasoning, rationality, discrimination, efficiency, strength, vigor,
analysis, and creativity, that is, it governs vital processes in the
body.It’s also thought that Pingala regulates the entire right side of the
body. To control Pingala, one needs to manipulate the breath through the
right nostril.
It’s also thought that Pingala Nadi can control the Sympathetic Nervous
System (SNS), which is part of the Autonomic Nervous System (ANS). The SNS
is considered to be responsible for the autonomous “fight or flight” stress
and challenge response. In those situations, the SNS tends to speed up
one’s heart rate, deliver more blood to areas of the body that need more
oxygen, or triggers other responses that help to face difficult or
dangerous situations.
A particularity of Pingala Nadi is that it seems to be connected with the
right testicle in men. Additionally, Pingala is associated with the color
red and stands symbolically for the sun qualities.
And every morning when you get up if carefully you observe yourself the
breathing pattern, you will notice the alterations naturally happening by
yourself. K Rajaram IRS (Kindly vide how many upanishads speak about it
and it means we are forced to learn it only threougha doctor as we did not
read any one of them)

3) It takes about 45–60 seconds for the whole blood to travel through the
whole body and return back to the heart for one time
KR: The statement that it takes about 45–60 seconds for blood to travel
through the whole body and return to the heart is generally accurate for a
healthy adult at rest. Here’s a bit more detail on how this works:
Circulatory System: Blood circulation through the body is a continuous
process involving the heart, arteries, veins, and capillaries. Blood
travels from the heart to the various organs and tissues via the arteries,
and then returns to the heart through the veins.
Circulation Time: On average, the time it takes for blood to complete one
full circuit around the body (from the heart, through the arteries, into
the capillaries, and back through the veins to the heart) is about 60
seconds. This can vary based on factors such as a person’s heart rate,
blood pressure, and overall health.
Heart Rate Impact: The speed of circulation is influenced by the heart
rate. For example, during physical activity, the heart rate increases,
which can speed up the circulation time. Conversely, at rest, the heart
rate slows down, which might lengthen the circulation time slightly.
Cardiac Output: The heart pumps blood with each beat, and the amount of
blood pumped per minute (cardiac output) and the rate at which the heart
beats (heart rate) both play roles in determining the circulation time.
Understanding these details provides insight into the efficiency of the
circulatory system and how it supports overall bodily functions.
4) Blood makes up about 8 percent of your total body weight.
KR: Yes, that’s correct. Blood typically makes up about 7-8% of your total
body weight. Here are some additional details:
Average Blood Volume: For an average adult, this translates to
approximately 4.5 to 6 liters of blood. Blood volume can vary based on
factors like age, sex, body size, and overall health.
Blood Components: Blood is composed of several components, including red
blood cells, white blood cells, platelets, and plasma. Plasma, the liquid
part of blood, makes up about 55% of the total blood volume, while cells
and platelets make up the remaining 45%.
Importance of Blood Volume: Maintaining the right blood volume is crucial
for effective circulation, oxygen delivery to tissues, and overall
physiological balance.
Blood Volume Changes: Blood volume can fluctuate due to various factors,
such as hydration levels, health conditions, and physical activity. For
instance, during dehydration, blood volume may decrease, while it can
increase with certain medical treatments or conditions. Understanding the
percentage of body weight that blood constitutes helps highlight its
significance in maintaining various bodily functions and overall health.
6) Nose is the only part of our body that never stops growing
KR: ONLY IS ERRANEOUS. The statement that the nose is the only part of
our body that never stops growing is a bit of an exaggeration, but there is
some truth to it. Here’s a more nuanced look:
Nose and Ears: The nose and ears are often cited as body parts that
continue to change throughout a person’s life. This is primarily due to the
ongoing growth of cartilage. Unlike bone, cartilage continues to grow and
change, albeit at a slower rate, throughout life.
Cartilage Growth: While bones stop growing after adolescence, cartilage,
which makes up a significant portion of the nose and ears, can continue to
grow and change due to natural aging processes. This means that the nose
and ears can appear to get larger over time.
Aging Effects: As people age, the elasticity of the skin and the structure
of the cartilage can change. This might make the nose and ears look larger,
but it’s more about changes in the tissue rather than continual growth.
Overall Growth: While the nose and ears may appear to grow with age, it’s
not as dramatic as continuous growth throughout life. Other parts of the
body, such as skin, can also undergo changes due to factors like aging, but
these aren’t growth in the traditional sense.
In summary, the nose and ears are notable for their continued changes
throughout life due to cartilage growth, but they’re not the only parts of
the body that undergo changes as we age.
11) Blushing is caused by a rush of adrenaline
Kr: *Blushing is not directly caused by a rush of adrenaline, but
adrenaline can play a role in the process*. Here’s a more detailed look at
what causes blushing:
Blushing Mechanism: Blushing primarily occurs due to the dilation of blood
vessels in the face, which increases blood flow to the skin. This is often
a response to various emotional or physiological triggers.
Sympathetic Nervous System: Blushing is controlled by the sympathetic
nervous system, which is part of the autonomic nervous system that
regulates involuntary bodily functions. When this system is activated, it
can cause the blood vessels in the face to dilate.
Emotional Triggers: Common triggers for blushing include feelings of
embarrassment, shyness, or nervousness. The body's response to these
emotions involves increased sympathetic nervous system activity, which can
include a release of adrenaline (epinephrine).
Adrenaline’s Role: Adrenaline is a hormone that prepares the body for a
“fight or flight” response, causing various physiological changes such as
increased heart rate and blood pressure. While adrenaline can influence
blushing, it’s not the sole cause. The dilation of blood vessels in the
face is more directly responsible for the visible reddening.
Vascular Response: The dilation of facial blood vessels that leads to
blushing is influenced by various factors, including emotional responses,
but is not exclusively due to adrenaline.
----------------------------------------------------------------------------
Q2 What 3 ancient tools can we still use today, without any
alterations (because they worked so perfectly)?
KR: Without any alterations is erraneous: The assertion that the
mallet, rope, and saw are three tools that have remained unchanged from the
past until now is not entirely accurate. Here’s a more detailed look at
these tools and how they have evolved:
Mallet: Historical Use: Mallets have been used for thousands of years.
Early mallets were simple wooden tools used for tasks like pounding,
striking, or shaping materials.
Evolution: Modern mallets still perform the same basic functions but come
in various materials and designs. For example, contemporary mallets might
have heads made from rubber, plastic, or metal, and handles designed for
ergonomic use.
Rope: Historical Use: Rope has been used since ancient times for tying,
lifting, and securing objects. Early ropes were made from natural fibers
like hemp, sisal, or jute.
Evolution: While the fundamental purpose of rope remains the same, the
materials and manufacturing processes have advanced significantly. Modern
ropes are often made from synthetic fibers such as nylon or polyester,
which offer enhanced strength, durability, and flexibility compared to
traditional natural fibers.
Saw: Historical Use: Saws have been used for cutting wood and other
materials for thousands of years. Early saws were typically made from iron
or steel and featured a simple blade design.
Evolution: Saws have seen substantial technological advancements. Modern
saws come in various types, including hand saws, power saws, and
specialized saws for different materials. The blades are often made from
advanced materials, and power saws incorporate electric or battery-powered
motors for efficiency.
In summary, while the basic functions of the mallet, rope, and saw have
remained consistent over time, their designs, materials, and manufacturing
techniques have evolved significantly.
Q3 What was very useful when it first came out but is useless today?
KR A WRONG ESTIMATE SIR: Yes, silos are *still widely used around
the world.* Here’s a closer look at their roles and applications:
Agricultural Use: Storage of Grains: Silos are commonly used on farms and
in agricultural operations to store grains like wheat, corn, and soybeans.
They protect the grains from environmental factors and pests while
maintaining their quality.
Feed Storage: Silos are also used to store animal feed. These silos can be
designed to handle large quantities of feed for livestock.
Industrial Use: Bulk Material Storage: In industrial settings, silos are
used to store a variety of bulk materials, including cement, coal, and
other raw materials. They facilitate the efficient handling and
distribution of these materials.
Manufacturing: Some manufacturing facilities use silos for storing
ingredients or components necessary for production processes.
Modern Developments: Advanced Designs: Modern silos come in various
designs and materials, including concrete, steel, and even reinforced
plastic. They can be equipped with advanced technologies for monitoring and
managing the stored materials.
Technology Integration: Many silos now feature automated systems for
filling, emptying, and maintaining the stored materials, enhancing
efficiency and reducing labor costs.
Environmental and Safety Considerations: Maintenance: Regular maintenance
is crucial to ensure that silos remain safe and functional. Issues such as
structural integrity and the management of potential hazards are important
for preventing accidents and ensuring efficient operation.
Overall, silos continue to be a vital part of agricultural and industrial
infrastructure, playing a key role in the storage and management of various
materials.
Here are some specific examples of places where silos are commonly used
around the world:
Agricultural Operations:
Midwestern United States: In states like Iowa, Nebraska, and Kansas, silos
are extensively used on farms to store harvested grains such as corn,
wheat, and soybeans.
Southern Australia: In regions like Victoria and South Australia, silos are
employed on grain farms to store crops before they are transported to
processing facilities or export points.
Industrial Facilities:
Cement Plants: Facilities such as the Lafarge Cement plant in France
or the HeidelbergCement
plant in Germany use silos to store cement and other bulk materials.
Coal Storage: Power plants, like those in the United Kingdom and the United
States, use silos to store coal before it is burned to generate electricity.
Manufacturing Sites:
Food Processing Plants: Large food processing facilities, such as those
operated by companies like Cargill or Nestlé, use silos to store
ingredients like sugar, flour, or feed components.
Chemical Plants: Facilities involved in chemical production, such as those
in the chemical hubs of the Gulf Coast in the United States, use silos to
manage bulk chemicals and raw materials.
Specialty Storage:
Wine Production: Wineries, such as those in Napa Valley, California, and
Bordeaux, France, use silos and tanks to store and ferment wine grapes.
Silage Storage: Dairy farms and livestock operations, including those in
New Zealand and Ireland, use silos to store silage, a type of fermented
feed for animals.
Any more have i to say ; i have not brought india at all though.......
Q5 Steam engines: Still encuclopedia says use is there still though not
as once it was used to be. Yes, steam engines are still used in certain
contexts, though their use is much less common than in the past. Here are
some areas where steam engines are still in operation in 2024:
Heritage Railways: Many heritage railways around the world still operate
steam locomotives as a way to preserve and showcase historical technology.
These railways are often tourist attractions, offering a nostalgic
experience of train travel from earlier eras.
Industrial Applications: In some industries, particularly in remote or
developing regions, steam engines are still used to generate power or
operate machinery. This is less common today but can be found in specific
applications where more modern technology is not available or practical.
Marine Vessels: Some older ships, especially those that have been preserved
as museum ships or are still in use for historical purposes, may have steam
engines. Additionally, steam turbines are used in certain naval vessels and
power plants, although these are more advanced and efficient than
traditional steam engines.
Electricity Generation: Steam turbines are widely used in power plants to
generate electricity. While these are not the same as traditional steam
engines, they do rely on the same basic principle of using steam to turn a
turbine and generate power. These turbines are a key component of many
coal, nuclear, and natural gas power plants.
Research and Education: Steam engines are also used in educational settings
to demonstrate principles of thermodynamics and mechanical engineering.
Overall, while steam engines are no longer the dominant technology they
once were, they continue to have a place in certain niche areas.
