After exchange, the arteries transport oxygenated blood from the heart to the tissues. Oxygen diffuses from tissue capillaries through interstitial fluid, cell membranes, cytoplasm, and finally reaches the mitochondria.

pired air.The lungs fill the thoracic cavity, and although they are not physically attached, the lungs and chest wall move together during respirationPulmonary System10CONTENTSPULMONARY SYSTEM PHYSIOLOGY MAPSTRUCTURE AND FUNCTION OF THE RESPIRATORYSYSTEMUpper Airways and LarynxLower AirwaysPleuraMus Ebook Elsevier''s integrated physiology: Part 2 effectively couples the movement of the lungs to the movement of the chest wall.Within the thorax, the elastic recoil of the lungs pulls the lungs away from the chest wall. Conversely, the recoil of the thorax pulls the chest wall away from the lungs. These opposing forces cause the interpleural pr Ebook Elsevier''s integrated physiology: Part 2essure to be negative, about -4 mm Hg at rest, and even more negative during inspiration.Alveoli must remain open to participate in gas exchange.

Alveolar hypoxia causes pulmonary vascular smooth muscle to vasoconstrict and to direct pulmonary blood flow away from areas of poor ventilation.
