A gland is a cell or an organ in an animal's body that produces and secretes different substances that the organism needs, either into the bloodstream or into a body cavity or outer surface.[1] A gland may also function to remove unwanted substances such as urine from the body.[2]
There are two types of gland each with a different method of secretion. Endocrine glands are ductless and secrete their products, hormones, directly into interstitial spaces to be taken up into the bloodstream. Exocrine glands secrete their products through a duct into a body cavity or outer surface.[2]
Glands are mostly composed of epithelial tissue, and typically have a supporting framework of connective tissue, and a capsule.[2]
