Most of the Exchange Surfaces of Multicellular Animals are Lined

Question

Most of the exchange surfaces of multicellular animals are lined with
A) connective tissue.
B) smooth muscle cells.
C) neural tissue.
D) epithelial tissue.
E) adipose tissue.

Accepted Answer

Epithelial tissue is the most appropriate choice since it is responsible for lining most of the exchange surfaces of multicellular animals, such as the lining of the lungs, intestines, and capillaries.

Other choices are incorrect because connective tissue provides support and structure, smooth muscle cells are involved in movement, neural tissue is responsible for communication and signaling, and adipose tissue is involved in energy storage and insulation.
