Answer:
Epithelium is one of only 4 types of human body tissues. Like all types, it is formed by cells within an extracellular matrix (ECM).
The cells in this tissue are tightly packed within a thin ECM. Forming sheets that cover the internal and external body surfaces (surface epithelium) and secreting organs (glandular epithelium). Functions of epithelial tissue are secretion, protection, absorption, transportation and special sensory receptive.
