Where is squamous epithelial tissue found?

282.3k+ views
Hint: Epithelial tissues are found all over the body. They cover all body surfaces, line body cavities and hollow organs, and make up the majority of gland tissue

Complete answer:
The epithelium tissue serves as a barrier between various environments, and virtually all substances must move through it. As an interface tissue, epithelium performs a variety of functions, including:
Radiation, desiccation, chemicals, and physical damage protection for the underlying tissues
Absorption of substances in the lining of the digestive tract with distinct modifications.
Absorption of substances in the lining of the digestive tract with distinct modifications.
Chemical regulation and excretion between the underlying tissues and the body cavity.
Hormone injection into the blood vascular system. Sweat, mucus, enzymes, and other products delivered by ducts are secreted by the glandular epithelium.
Perception of touch.
Squamous Epithelium
The cells of simple squamous epithelium are smooth and arranged in a single layer. This single layer is thin enough to form a membrane through which compounds can move passively. This epithelial form is found in capillary walls, pericardium linings, and alveolar linings of the lungs. Allows liquids to move by through diffusion and filtration, and secretes lubricating substances.

The number of layers and the form of the cells in the upper layers distinguish epithelial tissues. There are eight specific types of epithelium: six are classified by the number of cells as well as their shape; two are called by the type of cell present in them (squamous). The number of cells, the shape of those cells, and the form of epithelial tissue are used to classify it.
