NEET BIOLOGY

Detailed explanation-1: -Simple squamous epithelia are found lining the cavities of the body including the pericardial, pleural, and peritoneal cavities, or in areas where passive diffusion occurs, such as glomeruli in the kidney and alveoli in the respiratory tract.

Detailed explanation-2: -Explanation: Alveoli are the site of gas exchange in the lungs. Because rapid diffusion of gases is necessary between the capillaries and the alveoli, a very thin epithelial layer is needed. As a result, alveoli use simple squamous epithelium so that gases can easily diffuses to and from the bloodstream.

Detailed explanation-3: -Simple squamous epithelium This type of epithelia lines the inner surface of all blood vessels (endothelium), forms the wall of alveolar sacs in the lung and lines the body cavities (mesothelium). The primary function of simple squamous epithelia is to facilitate diffusion of gases and small molecules.

Detailed explanation-4: -Endothelium = the simple squamous epithelium lining blood vessels.

Detailed explanation-5: -In the kidney, simple squamous epithelium lines the Bowman’s capsule and the glomerulus (Figure 2). In this case, the ability of simple squamous epithelium to provide rapid filtration and diffusion is instrumental to the kidney’s function, as the kidney filters about 180 liters of blood per day.
