Question

Describe the structure and functions of epithelium. (not for each type, i need it in general for all epithelial tissues)

Answer 1

In epithelial tissue, cells are closely packed with little or no extracellular matrix except for the basal lamina that separates the epithelium from underlying tissue. The main functions of epithelia are protection from the environment, coverage, secretion and excretion, absorption, and filtration.
