Page 522 Endocrine system includes… Pituitary Gland Adrenal Gland Thyroid Gland Hypothalamus Pancreas Thymus Its function is to… Control many of the body’s activities as well as long- term changes. Structure info: Pituitary Gland ● controls many body activities Adrenal Gland ● produces the hormone adrenaline that triggers the body to respond to emergency situations Thyroid Gland ● Controls the release of energy from food Hypothalamus ● part of the brain that links the nervous system to the endocrine system Structure info: Pancreas ● produces the hormones insulin and glucagon that control the level of glucose in the blood. Thymus ● controls the development of cells in the immune system. How is structure and function related? The glands in conjunction with the nervous system release hormones that control the body’s activities and changes. Taking care… Excessive drug use, such as steroids, can alter the chemical/hormone release in the body causing unwanted changes Eat balanced diet and drink plenty of water Exercise regularly Diseases/Conditions of the Endocrine system: Hyperthyroidism and Hypothyroidism - Thyroid hormones regulate how the body breaks down food and either uses that energy immediately or stores it for the future. In other words, our thyroid hormones regulate our body's metabolism. Hypo=low metabolism /Hyper=high metabolism Diabetes - occurs when the pancreas, a gland behind the stomach, does not produce enough of the hormone insulin. Insulin is necessary to carry sugar from the bloodstream into the cells. Facts… When a hormone enters the bloodstream, it does not affect any other cell other than the one it was sent out for, the target cell. The chemical structure of the hormone and target cell fit together like puzzle pieces. The pituitary gland is about the size of a pea.
