As the diaphragm moves down or flattens, the ribs flare outward, the lungs get bigger and air is drawn in. As the diaphragm relaxes, air leaves the lungs and they spring back to their original position. The lungs, like balloons, need energy to blow up but no energy is needed to let air out.
When the brain knows how much oxygen is needed, it sends messages through the nerve supply to the muscles which work to allow breathing to take place. These are, the diaphragm (the main breathing muscle), the intercostal muscles (which assist the diaphragm), and the accessory muscles.
The lungs flank the heart and great vessels in the chest cavity. (Source: Gray's Anatomy of the Human Body, 20th ed. 1918.) Functions In this chaper we will discuss the four processes of respiration. They are: 1. BREATHING or ventilation 2. EXTERNAL RESPIRATION, which is the exchange of gases (oxygen and carbon dioxide) between inhaled air and ...
