Respiratory System General Respiration is the process in which gases are exchanged. This process is accomplished by the respiratory system, which removes CO 2 from the blood and absorbs O 2 from inhaled air. The exchange of gases between the air in the alveoli of the lungs and the blood in the capillaries of the lung is called external respiration. In contrast, the exchange of gases between the blood in the capillaries at the tissues and the interstitial fluid is called internal respiration. The cells in the body consume O 2 during aerobic cellular respiration and generate CO 2 as a waste product. The process of ventilation brings fresh air into the lungs while exhaling CO 2 . Anatomy and Physiology The respiratory system consists of the conduction organs and the respiratory structures . The conducting division includes the nose, pharynx , larynx , trachea , bronchi , and lungs (bronchioles ). The respiratory division is the alveoli and alveolar sacs . Nasal Cavity
