THE ENDOCRINE SYSTEM

The Endocrine System (ES) is the part of the nervous systems which controls the secretion of hormones through a set of glands spread out within the human body. This diagram illustrates the the location of the different glands.

The Pineal gland secretes Melatonin which induces sleep and lowers body temperature. Beneath this gland is the Pituitary gland which produces a variety of hormones and is known to control puberty and the production of growth hormones.

Next in the throat region are the Parathyroid glands. These glands are responsible for monitoring the amount of calcium in bones and in the blood. Beneath them is the Thyroid gland which controls metabolism and bone growth. 

In the abdomen is the Pancreas which controls the production of insulin and regulates the levels of sugar in the blood. The Adrenal glands are responsible for the breakdown of fat, the synthesizing of proteins, regulates kidney processes, and controls the Androgen hormone which controls masculinity. These glands also control oxygen and blood flow the the brain and regulate pain.

Finally the Ovaries and Testes regulate growth, the reproductive cycle, secondary growth characteristics (breasts, body hair, etc.) and control many of the body's key processes.
