About Respiratory System
The respiratory system includes the air passages, lungs, pleura, alveoli and the mechanics of breathing. It explains pulmonary ventilation, gas exchange, oxygen and carbon dioxide transport, regulation of breathing, and the difference between external respiration in the lungs and internal respiration in body tissues.
