Gas Exchange with Tissues Gas exchange occurs in the alveoli so that oxygen is loaded into the bloodstream and carbon dioxide is unloaded from the bloodstream. Afterwards, oxygen is brought to the left side of the heart via the pulmonary vein, which pumps it into systemic circulation.

WebThe alveolar membrane is the gas exchange surface. Gas exchange in the lung. When you inhale oxygen, it enters the lungs and travels to the alveoli. Cells lining alveoli and capillaries carrying blood are in close contact with each other. The barrier thickness averages to 1 micron - that’s 1/10 000 of a centimetre! Webad 1 - Deoxygenated blood is brought to the alveoli. ad 2 - Diaphragm and intercostal muscles cause the volume of the lungs to increase and decrease in volume by CONTRACTIONS. This causes ventilation to occur. This in turn ensures a supply of high oxygen and low carbon dioxide AIR to the alveoli. Click the card to flip 👆.
