• No apical or free surface

• Attached to a thick basement membrane

• Lacks blood vessels

Where can epithelial tissue be found in the body?

• Only in the respiratory tract

• Only in the digestive tract

• In the skin, respiratory tract, digestive tract, and glands

• Nowhere in the body

What is the function of epithelial tissue in the skin?

• Protection from harmful substances

• Secretion of hormones

• Absorption of nutrients

• Exchange of gases

Which type of epithelial cell is found in the air sacs of the lungs?
