WebIn other words, the pressure is directly proportional to surface tension and inversely proportional to the radius of the alveolus. What this means for the lungs is that if the pull of the surface tension is the same, the large alveoli would have a lower internal pressure and smaller alveoli would have a higher internal pressure.

WebAlveoli are made of thin-walled, parenchymal cells that are in direct contact with capillaries of the circulatory system. This ensures that oxygen will diffuse from alveoli into the blood and that carbon dioxide produced by cells as a waste product will diffuse from the blood into alveoli to be exhaled. WebPulmonary alveolus ( plural: alveoli) are tiny air sacs that function as basic respiratory units. It is a hollow cup-shaped cavity in the lung parenchyma, where gas exchange takes place. … WebAlveoli function as the site of gas exchange, and hence have specialised structural features to help fulfil this role: They have a very thin epithelial layer (one cell thick) to minimise diffusion distances for respiratory gases They are surrounded by a rich capillary network to increase the capacity for gas exchange with the blood language arts standards illinois
