S. upply oxygen and eliminate carbon dioxide. Regulate pH of blood. Structure of Respiratory System. Respiratory tract is made up of two zones. 4 distinct events. Pulmonary ventilation. : air is moved in and out of the lungs. External respiration. : gas exchange between blood and alveoli. Respiratory gas transport. : CV system transports oxygen and carbon dioxide between lungs & tissues (discussed in Blood chapter). 4 Parts of Respiration. Pulmonary . ventilation. - . air moving into and out . of lungs. External respiration. - gas . exchange; blood - alveoli. Respiratory gas transport. - transport of . gases via bloodstream. and Disorders. Gas Exchange. Gas exchange occurs in the alveoli due to the difference in the partial pressures of oxygen and carbon dioxide in the capillary blood and the alveoli.. Since the concentration of oxygen is greater in the alveoli, it diffuses into the capillary blood.. Inhalation. Nasal cavity. Hairs: filter air. Mucus: filters & moistens. Blood vessels: warm air. • . Pharnyx. (throat). • Larynx (voice box)- glottis, epiglottis. • Trachea (wind pipe)- mucus & hairs.. Objectives. Understand normal mechanisms and regulation of acid-base balance. Interpret blood gases. Understand the effects of acidosis and alkalosis. Evaluate and manage acidosis and alkalosis. Normal Physiology.

Dr. . Shaimaa. . Munther. . Physiology of the Respiratory system. Overview . Respiration, includes two processes:. External respiration,. the absorption of O2 and removal of CO2 from the body as a whole. Respiration:. . Two integrated processes: external respiration and internal . respiration.. External . respiration. : . exchange of gases between . blood, lungs and . external environment; . gas . diffusion . BACKGROUND-Cellular Respiration. Oxygen . is used by cells. Oxygen is needed to convert glucose to ATP. Carbon dioxide is a waste product. Body cells die if respiration fails. FUNCTIONS. Supplies . body with oxygen and removes carbon dioxide.
