Gland - Definition


A gland is an organ of varying size whose role is to manufacture various bodily substances.

The human body contains several types of glands, each belonging to either the category of Endocrine glands or Exocrine glands. Each of these glands performs a separate function that ensures the correct functioning of the body.

The liver, for example, is a very important gland for digestion. It secretes bile, a liquid that helps the body to absorb dietary fat. Salivary glands deliver saliva into the mouth. Sweat glands, present everywhere under the skin, excrete sweat. This phenomenon aids in lowering overall body temperature.
