Final answer:
The mucous membranes and skin are both epithelial membranes that provide protective functions for the body, with mucous membranes also involved in secretion and absorption.
Step-by-step explanation:
The question, "Functionally and characteristically, can you relate the mucous membranes of the body to the skin?" addresses the biological similarity between mucous membranes and the skin. The answer to this inquiry is true. Both the mucous membranes and the skin are types of epithelial membranes made up of epithelium attached to a layer of connective tissue. The skin is an example of a cutaneous membrane, while the mucous membranes line the body cavities and hollow passageways that are exposed to the external environment, such as the digestive, respiratory, excretory, and reproductive tracts. These membranes serve a protective function, among others, and the mucous membranes are also involved in secretion and absorption. While the outer layer of skin is tough and provides a barrier against pathogens, mucous membranes cover the organs exposed to the outside world with a protective layer of mucus.
