alveoli
What is the function of simple squamous epithelium of the alveoli?
The alveoli is just one cell layer thick so that diffusion of gasses between the capillaries and the alveoli is easy. Simple squamous epithelium are found in the capillary walls and the alveolar walls. They are thin so diffusion is easy.
Why are the walls of the alveoli one cell thick?
The reason for this is that oxygen and carbon dioxide need to diffuse through this membrane very quickly to re-oxygenate the blood. The thicker the barrier, the longer the process, and since breathing is rather rapid it needs to happen fast.
