  5. What Is the Endocrine System? • The endocrine system regulates long-term changes in the body such as growth and development. • It also controls many of your body’s daily activities.

  6. Endocrine Glands • Your endocrine (EN duh krin) system is made up of a group of organs, called endocrine glands. • An endocrine gland produces and releases chemical substances that signal changes in other parts of the body. • Endocrine glands release substances directly into the bloodstream.

  7. Hormones • A chemical substance produced by an endocrine gland is known as a hormone. • You can think of a hormone as a chemical messenger. • The endocrine system is kept in balance by the coordinated action of various hormones.

  8. Functions of the Endocrine Glands The endocrine glands include the • hypothalamus • pituitary gland • thyroid and parathyroid glands • thymus gland • adrenal glands • pancreas • reproductive glands

  9. The Endocrine System Thyroid GlandThe thyroid gland regulates the body’s overall metabolic rate and controls calcium levels in the bloodstream. Parathyroid GlandsFour tiny parathyroid glands regulate levels of calcium and phosphorus––minerals that are necessary for proper bone and tooth formation and for muscle and nerve activity. PancreasThe pancreas is a large gland, located behind the stomach, that controls sugar levels in the blood.

  10. HypothalamusThe hypothalamus links the nervous system and the endocrine system and controls many of the pituitary gland functions. The Endocrine System Pituitary GlandThe pituitary gland controls other endocrine glands and regulates growth rate, reproduction, and metabolism. Thymus GlandHormones released by the thymus gland help the immune system develop during childhood. By adolescence, this gland has shrunkconsiderably in size. Adrenal GlandsThese glands release several hormones. Adrenaline triggers the body’s response to sudden stress. Other hormones affect salt and water balance in the kidneys and general metabolism.

  11. The Endocrine System OvariesThe female reproductive glands release sex hormones that regulate egg maturation and control changes in a female’s body at puberty. TestesThe male reproductive glands release a sex hormone that regulates sperm production and control changes in a male’s body at puberty.
