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 air we inhale enters our body through our nostrils. It then passes through the nasal cavity, the pharynx, the larynx and finally enters the windpipe, also known as the trachea. The trachea branches into bronchi which sends air into both the lungs.
Detailed explanation-3: -The air enters the body through the nostrils and passes through the windpipe, bronchioles and enters the alveoli. The oxygen from alveoli diffuses into the capillary. Now the oxygen in the lungs will be transported to all parts of the body.
