EPITHELIAL TISSUE
• Epithelial tissue originates from all 3 primary germ layers.
• Can be divided structurally or functionally.

FUNCTIONAL DIVISIONS OF EPITHELIAL TISSUE
• For covering and lining.
• To make up multicellular organs

AMORPHOUSE GROUND SUBSTANCE
The ground substance of connective tissue. It provides a matrix for the cells to adhere to. It varies in viscosity from fluid to gelatinous. The more cells present in the tissue, the less ground substance, etc.

• Serves as a barrier to the spread of bacteria
• Serves as a medium for the diffusion of nutrients and wastes between the cells and blood.
