simple squamous
Simple squamous epithelium is a single layer of flat, thin cells that line various structures in the body. This type of tissue is primarily found in areas where rapid diffusion or filtration occurs, such as in the alveoli of the lungs and the glomeruli of the kidneys. Its thinness allows for efficient exchange of gases, nutrients, and waste products.
The simple squamous cells are tightly packed but have a smooth surface, which reduces friction in areas like blood vessels, known as endothelium. This tissue plays a crucial role in maintaining the function of organs by facilitating processes like absorption and secretion in various systems throughout the body.
