Mucus is a slippery secretion of the lining of various membranes in the body (mucous membranes). It is a viscous colloid containing antiseptic enzymes (such as lysozyme) and immunoglobulins. Mucus is produced by goblet cells in the mucous membranes that cover the surfaces of the membranes. It is made up of mucins and inorganic salts suspended in water.

The mucous membranes (or mucosae; singular: mucosa) are linings of ectodermic origin, covered in epithelium, and are involved in absorption and secretion. They line various body cavities that are exposed to the external environment and internal organs. It is at several places continuous with skin: at the nostrils, the lips, the ears, the genital area, and the anus. The sticky, thick fluid secreted by the mucous membranes and gland is termed mucus. The term 'mucous membrane' refers to where they are found in the body and not every mucous membrane secretes mucus.
Body cavities featuring mucous membrane include most of the respiratory system. The glans penis (head of the penis) and the inside of the prepuce (foreskin) is mucous membrane, not skin.

mucus is a slippery secretion of the lining of various membranes in the body (mucous {mucus-like} membranes). mucus aids in the protection of the lungs by trapping foreign particles that enter the nose during normal breathing. additionally, it prevents tissues from drying out.
mucus is made by goblet cells in the mucous membranes that cover the surfaces of the membranes. it is made up of mucins and inorganic salts suspended in water.
in the digestive system, mucus is used as a lubricant for materials which must pass over membranes, e.g., food passing down the esophagus. in the respiratory system, it catches unknown matter and tries to prevent it from entering the body, especially in the nose. in the reproductive system, mucus aids the penis in entering the vagina during intercourse.
