PATHOLOGY

Detailed explanation-1: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.

Detailed explanation-2: -Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell.

Detailed explanation-3: -Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.

Detailed explanation-4: -Apoptosis. Apoptosis, also known as programmed cell death, is a regulated process that takes place throughout life and serves to eliminate necessary or damaged cells.
