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.
