PATHOLOGY

Detailed explanation-1: -If cells are no longer needed, they commit suicide by activating an intracellular death program. This process is therefore called programmed cell death, although it is more commonly called apoptosis (from a Greek word meaning “falling off, ‘’ as leaves from a tree).

Detailed explanation-2: -Apoptosis, e.g., programmed cell death, enables orchestrated development and cell removal in wounded or infected tissue. Experimental designs utilizing microgravity allow new insights into the role of apoptosis in wound healing.

Detailed explanation-3: -Definition. Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand.

Detailed explanation-4: -There are 4 stages of apoptosis: the initiation or stimulus for cell death, the active programmed cell death when the events become irreversible, phagocytosis of the dead cellular material, and inhibitory mechanisms of apoptosis.

Detailed explanation-5: -Ideally, the damaged cells are cleared by our immune systems through a process called apoptosis.
