Exocrine glands release substances like sweat and saliva through ducts on to the surface of the body. Exocrine glands include merocrine sweat glands, apocrine sweat glands and holocrine glands. Merocrine sweat glands, also known as eccrine sweat glands, are present through out the body and they release sweat that contains urea, electrolytes and many other compounds. Because the sweat contains urea, it contributes to body odor. Merocrine sweat glands are present throughout the body but they are found in high density in the thick skin like the palms of hands and soles of feet. Apocrine sweat glands are present in the nipples, groin, and axillary region and they become active once a person reaches puberty. Apocrine glands are associated with hair follicles and present in thin skin. Holocrine glands release sebum, an oily substance, on to the hair follicle which reduces drying of the skin.

Body membranes are tissues that wrap around an organ and line body cavities. Body membranes are made up of epithelial and connective tissue layer. Mucous membrane cover openings that are exposed to the outside world. For example, mucous membrane is present in the nose, respiratory tract, male and female reproductive systems, stomach and intestines. Epithelium of mucous membrane is attached to lamina propria, a loose connective tissue layer that stabilizes the epithelium in place. Goblet cells in the epithelium make mucus which is a liquid that protects the mucous membrane and prevents excessive friction. Therefore, when food goes down the esophagus into stomach and intestines, mucous membrane prevents the swallowing and digestion from being
