  1. 1. Chapter 39: Endocrine and Reproductive System
  2. 2. Hormones and Glands <ul><li>Hormones: </li></ul><ul><li>Chemicals that travel through the bloodstream sending messages </li></ul><ul><li>Affect cell activities </li></ul><ul><li>Last longer than nerve impulses </li></ul><ul><li>Glands: </li></ul><ul><li>Exocrine release secretions through ducts </li></ul><ul><li>Endocrine release secretions (hormones) into bloodstream </li></ul>Lily
  3. 3. Hormone Action <ul><li>Steroid Hormone </li></ul><ul><li>Can cross directly into cytoplasm </li></ul><ul><li>Lipids </li></ul><ul><li>Nonsteroid Hormone </li></ul><ul><li>Generally can’t pass through cell membranes </li></ul>Lily
  4. 4. Prostaglandins <ul><li>Produces small amounts of hormone like substances </li></ul><ul><li>Discovered first in prostate </li></ul><ul><li>Mortified fatty acids that produce a wide range of cells </li></ul><ul><li>Madeleine </li></ul>
  5. 5. Control of the Endocrine System <ul><li>Controlled by feedback methods that maintain homeostasis </li></ul><ul><li>The function of the thyroid gland is controlled by the anterior pituitary gland and the thyroid gland </li></ul><ul><li>Homeostatic control the materials broken down in the extracellular fluids and blood </li></ul><ul><li>Madeleine </li></ul>
  6. 6. Complementary Hormone Action <ul><li>Calcium: </li></ul><ul><li>Body regulates levels very carefully </li></ul><ul><li>One of the most important minerals in body </li></ul><ul><li>Without Calcium: </li></ul><ul><li>Blood can’t clot </li></ul><ul><li>Muscles can’t contract </li></ul><ul><li>Can’t transport across cell membrane </li></ul>Lily
  7. 7. Pituitary Gland and Hypothalamus <ul><li>Pituitary Gland: </li></ul><ul><li>Secretes 9 hormones that regulate lots of body functions </li></ul><ul><li>Controls actions of other endocrine glands </li></ul><ul><li>Hypothalamus </li></ul><ul><li>Controls pituitary gland’s secretions </li></ul>Lily
  8. 8. Thyroid and Parathyroid Glands <ul><li>Thyroid gland regulates body temperature </li></ul><ul><li>Makes thyroxin which contains amino acid tyrosine and mineral iodine </li></ul><ul><li>Hormones from both glands maintain homeostasis in blood calcium levels Madeleine </li></ul>Madeleine
  9. 9. Adrenal Glands <ul><li>Helps body with stress </li></ul><ul><li>Adrenal Cortex: </li></ul><ul><li>Produces hormone called corticosteriod </li></ul><ul><li>Adrenal Medulla: </li></ul><ul><li>Release of hormones controlled by the Sympathetic Nervous System </li></ul>Lily
  10. 10. Pancreas <ul><li>Glucagon and insulin excreted from the pancreas assist to maintain the level of glucose in the blood stable </li></ul><ul><li>Enzyme secretions break down food </li></ul><ul><li>When the pancreas doesn’t produce enough enough insulin diabetes can occur </li></ul><ul><li>Madeleine </li></ul>
  11. 11. Reproductive Glands <ul><li>Glands support two vital functions, production of gametes and secretion of sex hormones </li></ul><ul><li>Madeleine </li></ul>
