NEET BIOLOGY

Detailed explanation-1: -Epithelial tissues help in absorption of water and nutrients. Inside the body, epithelial cells form lining of mouth and alimentary canal and protect these organs. Epithelial tissues help in elimination of waste products.

Detailed explanation-2: -The epithelial tissue in your kidneys excrete waste, and the epithelial tissue in your sweat glands excrete sweat. Filtration: The epithelium of your respiratory tract filters out dirt and particles and cleans the air that you breathe in. Epithelial tissue in your kidneys filters your blood.

Detailed explanation-3: -Epithelial tissue in glands secrete hormones, enzymes, and other substances. Epithelial tissue in the kidneys excrete wastes, and in the sweat glands excrete perspiration. Epithelial tissue also has a sensory function as it contains sensory nerves in areas such as the skin, tongue, nose, and ears.

Detailed explanation-4: -Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

Detailed explanation-5: -Answer and Explanation: Since epithelial tissues do not have a blood supply, they obtain nutrients and remove wastes by a mechanism known as diffusion. Diffusion is the movement of molecules from a high amount to a low amount. The nutrients are diffused from the connective tissue present below the epithelial tissue.
