  1. EndocrineSystem Hormones and Organs that secrete

  2. Please label the diagram 1-10 Th: Feb 27, 2014 LT: I can identify and describe the role of hormones of the Endocrine system.

  3. 1. 2. 4. 3. 14. 5. 13. 6. 12. 11. 8. 7. 10. 9.

  4. Adrenal Gland • Aldosterone • Na+ retention by kidney • Cortisol • Stress hormone • Adrenaline • Fight or flight response

  5. Hypothalamus • GnRh/ Gonadotropin Releasing Hormone • Sex Drive

  6. Ovaries • Estrogen • Stimulates the development of female secondary sex characteristics • Produces an environment suitable for fertilization, implantation, and growth of embryo

  7. Pancreas • Insulin • Stimulates cells to take up glucose • Glucagon • Release glucose from glycogen • Maintain blood glucose levels

  8. parathyroid • Parathyroid Hormone/ PTH • Regulates the level of blood calcium and phosphate ions

  9. Pineal gland • Melatonin • Regulates circadian rhythms

  10. pituitary • Oxytocin • Uterine contraction/milk production • Vasopressin/ADH: Antidiuretic hormone • Causes kidneys to reduce water excretion • Growth Hormone/ Gonadotropin/ GH • Stimulates increase in size and mitotic rate of body cells, increases fat utilization • Promotes long bone growth

  11. Pituitary • Follicle Stimulating Hormone/ FSH • Development of ovarian follicles, stimulates follicular cells to secrete estrogen • In men, stimulation of sperm production • Luteinizing Hormone/ LH • Promotes secretion of sex hormones • In women, promotes egg release • Prolactin/PRL • Sustains milk production after birth

  12. Testes • Testosterone • Stimulates the development of male secondary sex characteristics

  13. thymus • Tyrosine • Produces T-Cells and lymphocytes

  14. thyroid • Thyroxin • Stimulates the consumption of O2 and thus the metabolism • Calcitonin • Lowers blood calcium • Deposits to bone

  15. I am Joe’s Pituitary Gland • Describe the pituitary gland. • Explain the pituitary gland’s role in the endocrine system. • List at least three hormones secreted by the pituitary gland. • What did doctors originally identify as the function of the pituitary gland and why? • Why is it believed that the pituitary gland is the answer to the cancer riddle? • Discuss one possible side affect of an injury to the pituitary gland.
