QUES ANSW MEDICAL-07-2022 20 Dear friends, These are informationcompiled as QA by me in 1998’s-2014’s and stored in my computer. They areposted by very learnt doctors inkidshealth.org etc.
Many improvements have come in medical field. Hence some information may have additions or some times changes. Theseare for general information, and for any health problem one hasto consult doctor. BEING COMPILATION THERE MAY BE ERRORS. Sincerely, R. Gopalakrishnan, 78, dated 31-07-2022 Q1What is wholeblood? What are its contents? A1 Theblood that flows through this network of veins and arteries is called *wholeblood*. Whole blood contains three types of blood cells: 1. redblood cells 2. white blood cells 3. platelets Q2 Which organ makeout blood? A2 Theseblood cells are mostly manufactured in the bone marrow Thesecells travel through the circulatory system suspended in a yellowish fluidcalled *plasma* (pronounced: *plaz*-muh).Plasma is 90%water and contains nutrients, proteins, hormones, and waste products. Whole bloodis a mixture of blood cells and plasma. The body containsmore RBCs than any other type of cell, and each has a life span ofabout 4 months Q3 What is thefunction of white blood cells? A3 Whiteblood cells (WBCs, and also called *leukocytes*, pronounced:*loo*-kuh-sytes)are a key part of the body's system for defending itselfagainst infection The bloodcontains far fewer white blood cells than red cells, although thebody can increase production of WBCs to fight infection There areseveral types of white blood cells, and their life spans vary from a few daysto months Someonewith an infection will often have a higher white cell count than when he or sheis well because more WBCs are being produced or are entering the bloodstream tobattle the infection Q4 What is thefunction of platelets cells? A4Platelets* (also called *thrombocytes*, pronounced: *throm*-buh-sytes) are tinyoval-shaped cells made in the bone marrow. They help in the clotting process Platelets survive only about 9 days in thebloodstream and are constantly being replaced by new cells. My note- About 15 years back I was admitted in ICU and on blood test found platelet value is veryless. Ten pouches of platelets were injected obtained from blood bank, andfortunately they were accepted anddeveloped. So I am here alive to post thisQA Q5 What is themeaning of clotting factors? A5 Bloodalso contains importantproteins called *clotting factors*, which arecritical to the clotting process. Although platelets alone can plug small bloodvessel leaks and temporarily stop or slow bleeding, the action ofclotting factors is needed to produce a strong, stable clot. Q6 Do some part ofthe blood alone can be replaced just like platelets or red celss alone? A6 YES An interesting thing about blood is that blood cells and some of thespecial proteins blood contains can be replaced or supplemented by givinga person blood from someone else. This process is called a transfusion. For example, someone can receive only platelets, red blood cells, or aclotting factor alone. My note- Aftertransfusion, a person may develop features like sniffing through the genes of the person who donated the blood. Q7 What is anemea due to kideney disease? A7 Anemia due to kidney disease.* Thekidneys produce erythropoietin, a hormone that stimulates production of red cells in the bone marrow. Kidney disease caninterfere with the production of this hormone. Q8 What is Neutropenia due to Cancerdisease? A8*Neutropenia* (pronounced: noo-truh-*pee*-nee-uh) occurs when there aren't enough of acertain type of white blood cell to protectthe body against bacterial infections. People who take certain chemotherapy drugs to treat cancer may developneutropenia. Q9 What is Thrombocytopenia due to in take of medicines? A9 Thrombocytopenia can happen when someone takescertain drugs or develops infections orleukemia or when the body uses up too many platelets Q10 When do bloodis taken from the veins? A10 If a larger blood sample is needed, thetechnician drawing the blood will clean the skin, insert a needle into a vein(usually in the arm or hand), and withdraw blood Q11 What is ultrasound scan?Can any body study the images produced? A11 Anultrasound is painless and uses high-frequency sound waves to bounce off organs and create a picture. Aspecial jelly is applied to the skin,and a handheld device is moved over the skin. The sound waves that come back produce animage on a screen. The images seen on most ultrasounds are difficult for the untrained eye to decipher, so a doctor will view theimage and interpret it. My note- It is anapproximation as told by my family physician. If there is slight variations on thisaccount, they are ignored as told by the doctor. Large variation only areconsidered -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
