Answer 1

Explanation:

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.

Answer 2

Epithelial tissue is classified primarily based on its layers, structure, and function.

Explanation:

• They are thin tissues that cover the entire body's exposed surface. They cover a variety of body parts, including the inner lining of the mouth, the digestive tract, secretory glands, and the lining of hollow organ sections such as the heart, lungs, eyes, and the urogenital tract.
• Tight junctions are structures that hold epithelial tissue cells together tightly. They are maintained by connective tissue termed the basement membrane and lack blood arteries and nerves.
• They have discrete basal domains that face the basement membrane and other apical surfaces of the organ lumen or the external environment, indicating polarity.
