How does diffusion occur within an alveolus
Did you know?
WebEach alveolus has an average diameter of 200 μm and is composed of a single epithelial layer of cells and extracellular matrix surrounded by capillaries. This is to ensure minimum diffusion distance (as little as 0.2 μm) between the atmosphere and the blood capillaries for gaseous exchange ( Ochs et al., 2004 ). WebIn the alveoli the concentration of oxygen is higher than in the capillaries. Therefore oxygen moves passively by diffusion into the capillaries. In contrast the concentration of carbon …

The oxygen we inhale is exchanged for carbon … WebSep 20, 2024 · Diffusion occurs when molecules move from an area of high concentration (of that molecule) to an area of low concentration. This occurs during the gaseous exchange as the blood in the capillaries surrounding the alveoli has a lower concentration of oxygen than the air in the alveoli which has just been inhaled.
