GENERAL HISTOLOGY

Detailed explanation-1: -Simple cuboidal epithelium functions include diffusion, absorption, secretion, and protection. Diffusion and absorption are the processes by which epithelial cells move substances out of the fluid or tissue they are surrounding, and secretion is the process of releasing substances into that fluid or tissue.

Detailed explanation-2: -The main function of the cuboidal cell epithelium is to help in absorption, excretion, and secretion. Cuboidal cells epithelium are single-layered cells that are shaped like a cuboid. These are found in small collecting ducts of kidneys, pancreas, and salivary glands.

Detailed explanation-3: -> Secretion: Cuboidal epithelium of digestive tract secretes digestive enzymes and endocrine glands secretes hormones. > Absorption and excretion: In auriferous tubules they absorb water from blood and help in their excretion.

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: -Squamous epithelium has a thin layer of flattened cells with irregular boundaries. Thus it helps in diffusion.
