It's a slippery secretion of the lining of the mucous membranes in the body. It is a viscous colloid containing antiseptic enzymes 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. Phlegm is a type of mucus that is restricted to the respiratory tract, while the term mucus refers to secretions of the nasal passages as well.

It is formed by goblet cells as a way to protect various surfaces in the body from bacteria (as in the nose) and to prevent erosion (as in the stomach where the pH is a very acidic 2).

It is secreted by cells which have that as their primary purpose.
