The Endocrine System 8th Grade 2011
What is the Endocrine System? • The Endocrine System is a series of small organs that secrete chemical messengers called hormones. • The hormones regulate mood, metabolism, growth, development, puberty, and tissue function. • The following slides tell more about the various glands of the endocrine system
Pituitary Gland: The Master Gland Located at the base of the brain and is the size of a pea Releases hormones into the blood to control other glands in the endocrine system The Pituitary Gland helps regulate the thyroid, helps the body turn food into energy, triggers the start of puberty, and turn on the production of breast milk It also regulates water in the body and blood pressure
Pancreas • The pancreas produces chemicals that are vital to proper digestion. • The pancreas regulates blood sugar by controlling insulin and glucagons. • Diabetes is a disease where the pancreas fails to properly function and create insulin. • Other diseases associated with the pancreas are pancreatic cancer, cystic fibrosis and pancreatitis
What is a Pineal Gland? • The Pineal Gland produces melatonin, a naturally occurring hormone, which is located in the brain. • Melatonin and Pineal Gland helps you regulate the biological rhythms and it also helps regulate wake and sleep cycles.

What is the Thymus Gland? • The Thymus Gland is located in the upper chest behind the sternum or breast bone. The main function of the Thymus is to provide an area for the lymphocytes (white blood cells) to mature into T-Cells. T-cells are specialized cells which destroy virally infected cells in the body.
Gonads • The gonads include the testes and the ovaries • Testicles are contained within the scrotum and produce the male reproductive hormones ( i.e. testosterone and androstenedione) • The testicles also produce sperm which is 50% of the reproductive system • The hormones that are produced in the testicles give men their aggressive and sexual drive. Physical features include the growth of body hair, male pattern baldness, and growth
Adrenal Glands • The adrenal glands are orange-colored endocrine glands which are located on the top of both kidneys. The adrenal glands are triangular shaped and measure about one-half inch in height and 3 inches in length. • The adrenal gland produces cortosol, which, in moderation, helps reduce stress. If overdosed, though, it can make you get sick and lose muscle mass as well. • Adrenal Glands produce noradrenalin and adrenaline. These hormones are produced when you are in a “fight or flight” situation and help regulate blood pressure, heart rate and metabolism.
