WebExchanging Oxygen and Carbon Dioxide. The primary function of the respiratory system is to take in oxygen and eliminate carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. WebThe alveoli are covered by a rich blood supply of capillaries- this provides a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.The alveoli are also highly folded, meaning there is a high surface area: volume ratio for gas exchange.Finally, the alveolar walls are only one cell thick, so the gases can … military pay differential policyWebThe lungs are the gas exchange surface in humans and so are adapted to maximise the exchange of gas by diffusion Inside the lungs there are many rounded alveolar sacs which give a very large surface area to volume ratio These alveoli are highly specialised structures military payday chart 2022
