Question

Epithelial tissue performs which of the following functions?

• A. Protection, secretion, respiration
• B. Protection, secretion, absorption
• C. Protection, secretion, digestion
• D. Secretion, absorption, digestion

Answer 1

The correct option is B Protection, secretion, absorption

The primary functions of epithelial tissue are:

(1) Protection: Protects tissues that lie beneath it (Example: skin)

(2) Secretion: Facilitates secretion of hormones, sweat, mucus enzymes, etc. (Example: the lining of the intestine secretes enzymes)

(3) Absorption: Facilitates absorption of materials (Example: absorption of digested food from the intestine)

(3) Movement: Facilitates movement of materials (Example: movement of mucus in the respiratory tract)

(4) Mechanical support: Provides mechanical support to the layers beneath the tissue (Example: the lining of kidney tubules)

So, the correct answer is - Protection, secretion, absorption.
