How gas exchange happens in our lungs
Web5 mrt. 2024 · Gas exchange in the lungs takes place across the thin walls of pulmonary arteries in tiny air sacs called alveoli. Oxygenated blood is transported by the circulatory system from lungs to tissues throughout the body. Gas exchange between blood and body cells occurs across the walls of peripheral capillaries. WebExplore the mechanics of the lungs and rib and diaphragm muscles involved in human respiration. Alveolar pressure fluctuations are caused by expansion and contraction of the lungs resulting from tensing and relaxing of the muscles of the chest and abdomen. Each small increment of expansion transiently increases the space enclosing lung air.

Web23 apr. 2024 · Loss of surface area occurs in diseases, such as emphysema, that destroy the lung architecture, and cause a loss of gas transfer. Likewise, any disease that causes thickening of the alveolar membrane, such as pulmonary fibrosis, increases the distance for, and resistance to, gas transfer. WebGas Exchange Between Alveolar Spaces and Capillaries The function of the respiratory system is to move two gases: oxygen and carbon dioxide. Gas exchange takes place in the millions of alveoli in the lungs and the …
