Respiratory System Diagram

This respiratory system diagram presents a structure of the respiratory system as well as an external respiration process, or breathing. The life actually occurs at a cellular level with Oxygen playing one of the most essential roles in biochemical and physiologic processes involved in cellular respiration. The internal or cellular respiration process in which glucose or other small molecules are oxidized in order to produce the vital energy is required for survival and reproduction of our cells and tissues. The respiratory system comprises the air passages organs (described in this respiratory system diagram) and the diaphragm.

The same gas-exchange principles shown in this diagram are what hyperbaric medicine builds on: raising ambient pressure multiplies the oxygen dissolved in plasma. For a practical explanation of how a hyperbaric chamber works, see this illustrated guide.
