The respiratory system is the body’s structure that allows us to breath. It is made up of several key areas including the nose and mouth, trachea and lungs. The respiratory system works very closely with the circulatory system. The purpose of breathing is for the body to obtain oxygen, a helpful molecule, and release carbon dioxide which is waste. Oxygen and carbon dioxide are carried by the blood. Breathing also allows us to talk. Normal adults breath about 12-16 times in one minute. When exercising, they may breath up to 45 times in a minute.
