Gas exchange within the alveoli
WebGas 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. WebAug 13, 2024 · Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases with the external environment and occurs in the alveoli of the lungs.

WebThe Alveoli Gas exchange occurs in the alveoli, which are single cell structures in the terminal portions of the lung. To move oxygen to the tissues, the entire blood volume (approximately 5 liters) passes through the lung each minute. The alveoli contain two cell types, epithelial (pulmonary) cells and endothelial (vascular) cells. WebThe exchange of these two gasses occurs by a process called diffusion.
