Histology.
What are the four major types of tissues?
Epithelial, Connective, Muscle, Nervous.
Where would you find epithelial tissue?
Cover’s most of the body’s external and internal surfaces and compromise most glands.

What is the function of muscle tissue?
Makes movements possible.
What do the cells of epithelial tissue do when they are closest to the basement membrane?
Readily divide.
What is a result from epithelial tissue being avascular?
Avascular (lack of blood cells)
Because they are avascular they rely on the vascularity of underlying connective tissue for nourishment and waste removal.
What are the functions of epithelial tissues?
The functions of epithelial tissue include protection, filtration, secretion and absorption.
