Document Summary

The transport of oxygen from air blood. The removal or co2 from the blood air. Forming a line of defense to airborne particles. The lungs are located in the thoracic cavity and are surrounded by the rib cage and the diaphragm. The airways consist of the nasal cavity and the mouth, which join tg at the pharynx. The trachea divides into 2 main bronchi (left and right) which continually divide into smaller and smaller bronchioles (smaller airways): primary bronchi (r and l branch) one in each lobe in the lung. The pulmonary artery delivers deoxygenated blood to the lungs, branches extensively to form a dense network of capillaries around each alveolus. From the capillaries, the o2-rich blood flows back into the left side of the heart through the pulmonary vein. ~300 million alveoli in a healthy human lung, each with a diameter of.
