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.
