Detailed explanation-1: -When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out).
Detailed explanation-2: -The DIAPHRAGM is the strong wall of muscle that separates your chest cavity from your abdominal cavity. By moving downward, it creates suction to draw in air and expand the lungs.
Detailed explanation-3: -Definition. Inhalation is a part of breathing where the air is taken into the lungs by creating negative pressure by the contraction of respiratory muscles and diaphragm. Exhalation is a part of breathing where the air is drawn out of the lungs by the relaxation of respiratory muscles.
