Document Summary

The respiratory system is responsible for the transport of oxygen from the air into the blood and the removal of carbon dioxide from the blood into the air. It is also responsible for controlling the ph of blood, and for temperature regulation. The lungs are suspended in the thoracic cavity and are surrounded by the chest wall. The thoracic cavity is separated from the abdominal cavity by the diaphragm, which is a powerful skeletal muscle below the ribs. The space between the lung and the chest wall is called the. The lung, chest wall, and diaphragm are elastic structures, which intrapleural space are very important. To move air from the environment to the lungs/alveoli. Like the airways, the pulmonary artery also branches extensively and eventually forms a dense network of capillaries that wrap around the alveoli. Gas exchange takes place in the alveoli at the blood-gas-barrier (bgb), which separates the blood in pulmonary capillaries from air in the alveoli.
