Question

question 37
what is the purpose of epithelial tissue?
a keep moisturized
b movement
c protection
d communication

Explanation:

Epithelial tissue covers the body surfaces and lines body cavities. Its main functions include protection (e.g., skin epithelium protects underlying tissues from physical, chemical, and biological damage), secretion, absorption, and filtration. Movement is mainly associated with muscle tissue. While some epithelial tissues may be moist (like in certain internal linings), "keep moisturized" is not the core purpose. Communication is more related to nervous tissue.

Answer:

C. protection
