PATHOLOGY

Detailed explanation-1: -Gangrene occurs when blood flow to a certain area of the body is interrupted. The lack of blood flow causes tissue to die. Gangrene often affects the fingers or toes.

Detailed explanation-2: -Technically, necrosis refers to the entire process of irreversible cell death, while gangrene is a term used to refer to tissue death due to some form of interrupted blood supply. However, unlike gangrene, the term necrosis doesn’t automatically imply a problem as a result of inadequate blood supply.

Detailed explanation-3: -Gangrene is a serious condition where a loss of blood supply causes body tissue to die. It can affect any part of the body but typically starts in the toes, feet, fingers and hands. Gangrene can occur as a result of an injury, infection or a long-term condition that affects blood circulation.
