Question

Alveoli, capillaries, and glomeruli capsules are all lined with simple squamous epithelium. What function is shared by these structures?

Answer 1

The common function of alveoli, capillaries, and glomeruli capsules is rapid diffusion of substances.

Step-by-step explanation:

• Usually simple squamous epithelium is present in body in locations where filtration and diffusion or selective transport is required.
• As in alveloi, gases exchanges from blood to air spaces through simple squamous tissues.
• In capillary and glomeruli capsules water and other material are filtered from blood cells.
• This simple squamous epithelium allows only small molecules to pass while restrict big molecules like blood cells.

Answer 2

The common function shared by alveoli, capillaries and glomerular capsules are lined with simple squamous epithelium so they are all involved where absorption or transport of the materials occur. The function of the squamous epithelium is mainly selective transmembrane transportation either by using the concentration gradient or by active transport by using the membrane bound carrier proteins.

The pulmonary alveoli are highly vascular in structure and are formed by a layer of the squamous epithelial cells and a network of capillaries.

The capillaries are also made up of squamous epithelial cells and gas exchange between the alveoli and blood vessels occurs through these capillaries.
