DEFINITION
Gland
A gland is an organ in the body made of a group of secreting cells. There are several kinds of glands in a human body some of the most common glands are
Salivary glands - secrete saliva
Sweat glands- secrete sweat
Mammary glands- secrete milk
Endocrine glands - secrete hormones
Types of glands
The glands are of two types based on the mode in which they are released or secreted.
Endocrine glands
These are ductless glands (no tube to carry to various parts).
Their secretions are directly released into the blood which carries them to various parts of the body.
Exocrine glands
The exocrine glands have ducts.
The secretions from these glands are carried through the ducts.
The ducts may open outside the body to release the secretions (e.g.sweat, milk) or may be released on to another surface within the body (e.g. Digestive juices)
