The respiratory system facilitates gas exchange from "summary" of Anatomy & Physiology by Kevin T. Patton
The respiratory system plays a crucial role in the exchange of gases within the body. This process involves the intake of oxygen and the removal of carbon dioxide. Through a series of intricate mechanisms, the respiratory system ensures that the body receives an adequate supply of oxygen while effectively eliminating carbon dioxide, a waste product of cellular respiration. One of the primary functions of the respiratory system is to facilitate the exchange of gases between the external environment and the body's internal tissues. This exchange occurs in the lungs, where oxygen from inhaled air diffuses into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled. This process is essential for maintaining the body's overall homeostasis and ensuring the proper functioning of various organ systems.
