  1. Made up of its glands and hormones The glands are called ductless The release hormones directly into the blood stream Endocrine System

  2. The blood stream transports hormones throughout the body. Each hormone acts on a certain type of tissue called its target tissue.

  3. Location: Base of Brain Hormone: Growth hormone Function: stimulates the elongation of bones in the body. Pituitary

  4. Controls the pituitary gland Receives information from the nervous system Hypothalamus

  5. Helps develop the immune system Thymus

  6. Location: embedded in back of thyroid gland. Hormone: Parathormone Function: Controls the metabolism of calcium Parathyroid

  7. Location: on top of kidney Hormone: Adrenaline Function: Raises blood sugar level and increases heart beat and breathing rates. Adrenal Gland

  8. Location: Pancreas Hormones: Insulin Function: Stimulates glucose uptake by cells. Hormone: Glucagon Function: Promote conversion (change of glycogen to glucose) Islets of lagerphones

  9. Hormone: estrogen Function: Help develop secondary characteristics in females. Ovary’s

  10. The testes secrete male sex hormones called androgens. Testosterone is an androgen that affects the secondary characteristics in men. The Testes

  11. Located in the neck in front of the trachea Thyroid gland releases the hormone thyroxine. Function: regulates the rate of metabolism. Thyroid Gland

  12. Not enough iodine in the diet (iodine defiance) Causes swelling of the thyroid gland Goiter

  13. Goiter

  14. Undersecretion of insulin. High blood sugar Diabetes

  15. Gigantism

  16. 12 year old boy Measure 6-5 Oversecreation of growth hormone Occurs during childhood Gigantism

  17. Tallest man 8 feet 11 inches.

  18. At 7'4" and 500 pounds, Andre the Giant could have been famous for his size alone. His drive, talent and ambition, however, proved to be as big as Andre himself, and the wrestler became legendary for his achievements in and out of the ring.
