PATHOLOGY

Detailed explanation-1: -The process of breathing, or respiration, is divided into two distinct phases. The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward.

Detailed explanation-2: -Breathing is a mechanical process where the air volume changes in the chest cavity. On the other hand, respiration is a biochemical process where oxygen is introduced into the bloodstream and carbon dioxide is expelled from the body.
