How Does the Human Body Eliminate Dead Cells?
The human body is a complicated system which operates much like a
self-contained city. Some organs produce new cells, others use cells to perform
their jobs, and eventually certain scavenger cells arrive to remove dead cells
from the system. In the case of the human body, these scavengers are
specialized white blood cells called macrophages. Macrophages remove dead cells
essentially by eating them, which helps to explain why the word macrophage
means "big eater" in Greek.
