Question

Quizplus · Accepted Answer

Epithelial tissue is responsible for lining the absorption surfaces of multicellular animals, including the digestive and respiratory systems. It is a thin layer of tightly packed cells that serves as a barrier and is involved in the exchange of substances between the organism and its environment. Connective, neural, smooth muscle, and adipose tissue are not responsible for lining these surfaces.
