Without your endocrine glands — and the hormones they release — your cells wouldn't know when to do important things. For instance, your bones wouldn't get the message that it's time for you to grow and get bigger. And your body wouldn't know that it's time to begin puberty, the body changes that turn kids into grownups. You have a variety of endocrine glands in different sizes and shapes located in different parts of the body. You might be surprised to learn that the pituitary say: pih-TOO-uh-ter-ee gland, which is about the size of a pea, is the "master gland" of the endocrine system.

Medically reviewed by Elaine K. Luo, M. Function Organs Hormones Diagram Conditions The endocrine system is a network of glands and organs located throughout the body. Endocrine system function. Thyroid hormones are important because they help kids' and teens' bones grow and develop, and they also play a role in the development of the brain and nervous system.
Parathyroids: Attached to the thyroid are four tiny glands that work together called the parathyroids pronounced: par-uh-THY-roydz.
They release parathyroid hormone, which controls the level of calcium in the blood with the help of calcitonin pronounced: kal-suh-TOE-nin , which the thyroid makes. The adrenal glands have two parts, each of which makes a set of hormones and has a different function:. Pineal: The pineal pronounced: pih-NEE-ul body, also called the pineal gland, is in the middle of the brain. It secretes melatonin pronounced: meh-luh-TOE-nin , a hormone that may help regulate when you sleep at night and when you wake in the morning.
Reproductive Glands: The gonads are the main source of sex hormones. Most people don't realize it, but both guys and girls have gonads. In guys the male gonads , or testes pronounced: TES-teez , are in the scrotum. They secrete hormones called androgens pronounced: AN-druh-junz , the most important of which is testosterone pronounced: tess-TOSS-tuh-rone.
These hormones tell a guy's body when it's time to make the changes associated with puberty, like penis and height growth, deepening voice, and growth in facial and pubic hair. Working with hormones from the pituitary gland, testosterone also tells a guy's body when it's time to make sperm in the testes.
A girl's gonads , the ovaries pronounced: OH-vuh-reez , are in her pelvis. Estrogen is involved when a girl starts puberty. During puberty, a girl will have breast growth, start to accumulate body fat around the hips and thighs, and have a growth spurt. Estrogen and progesterone are also involved in the regulation of a girl's menstrual cycle. These hormones also play a role in pregnancy. The thyroid gland and parathyroid glands are located in front of the neck, below the larynx voice box.
The thyroid plays an important role in the body's metabolism. The parathyroid glands play an important role in the regulation of the body's calcium balance. The thymus is located in the upper part of the chest and produces white blood cells that fight infections and destroy abnormal cells.
Adrenal gland. An adrenal gland is located on top of each kidney.
