Explanation:
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). This process, called gas exchange, is essential to life.
Detailed explanation-2: -The role of the respiratory system is to breathe in oxygen and breathe out carbon dioxide. This is known as respiration. The cells of the body use oxygen to perform functions that keep us alive.
Detailed explanation-3: -The O2 needed for cellular respiration is obtained via inhalation. The CO2 that is generated is removed from the body via exhalation.
