The Endocrine System

There is another system that works with the brain and nerves to keep the body in order. This is the endocrine or hormone system. It controls the rate we grow, our feelings of hunger, our body temperature, and more. Glands are organs that run the endocrine system. The pituitary gland, the pancreas, ovaries (only in females) or testes (only in males), the thyroid gland, the parathyroid gland, and the adrenal glands are organs that run the endocrine system.

HORMONE ACTION
A hormone is carried by the blood from the endocrine gland to the tissue.

The pituitary gland is about the size of a pea. It hangs down from the base of your brain. It is the most important endocrine gland in your body. It produces the hormone which controls growth. You grow faster at night because more hormone is released into your blood when you are asleep.
