Overview

The respiratory system consists of the nasal cavity, pharynx, larynx, trachea (windpipe), bronchi, and lungs. The respiratory system and the cardiovascular system take oxygen from the air and transport it to individual cells. Air enters the nasal cavity. Then the air passes into the pharynx. After that air reaches the larynx and then trachea, bronchial tree, and lungs. The lungs are the principal organs of the respiration. The right lung is larger than the left. The right lung has three lobes, and the left lung has two. The primary function of the lungs is to provide oxygen to the blood and to remove carbon dioxide from it. Respiration involves several important processes: 1) ventilation, the movement of air into and out of the respiratory passages and the lungs; 2) gas exchange between the air in the lungs and the blood; 3) transport of oxygen and carbon dioxide in the blood; and 4) gas exchange between the blood and the tissues.
