Which tissue lines organs and cavities?

• A. Connective tissue
• B. Nervous tissue
• C. Epithelial tissue
• D. Muscle tissue

Answer: (C)

Epithelial tissue lines organs and body cavities. It forms continuous sheets that cover the surfaces of the body and line hollow organs, ducts, and the cavities that surround internal organs. This placement lets epithelial cells act as a barrier and interface with the external environment, regulating what enters or leaves, providing protection, and often enabling absorption, secretion, or sensation. You can observe it lining the digestive tract, airways, urinary tract, and the serous membranes that enclose body cavities, as well as forming the outer skin layer. In contrast, connective tissue mainly supports and connects structures, nervous tissue transmits signals, and muscle tissue contracts to produce movement, so they don’t serve the lining role that epithelial tissue does.
