"Microvilli" Good Luck n.n
Fibrosis refers to the formation of excess of fibrous connective tissue in a tissue or an organ as a response to injury or damage. It is an exaggerated immune response or wound healing process affecting the functioning of the thickened organ. It affects various parts of the body. It critically affects the mucosa of the body. The mucosa or the mucous membrane consists of the epithelial tissue supporting the loose connective tissue called the lamina propria. The organs like the liver, lungs, heart and brain are primarily affected by fibrosis.
Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane.
hope this helps :)
