PCT Respiratory Therapy, 1ed

We usually think of respiration as the mechanical process of breathing, the exchange of air between the lungs and the external environment. This exchange of air at the lungs is called external respiration. In external respiration, oxygen is inhaled (inhaled air contains about 21% oxygen) into the air spaces (sacs) of the lungs and immediately passes into tiny blood vessels (capillaries) surrounding the air spaces. Simultaneously, carbon dioxide, a gas produced when oxygen and food combine in cells, passes from the capillary blood vessels into the air spaces of the lungs to be exhaled.

Whereas external respiration occurs between the outside environment and the capillary blood of the lungs, another form of respiration occurs simultaneously between the individual body cells and the tiny capillary blood vessels that surround them. This is internal (cellular) respiration, which involves an exchange of gases at the level of the cells within all organs of the body. Here, oxygen passes out of the capillaries into tissue cells. At the same time, carbon dioxide passes from tissue cells into the capillaries to travel to the lungs for exhalation.
