Transcript

  • 1. Adrenal, Pancreas, Pineal, Thymus, Gonads, Placenta (pg 8)
  • 2. Adrenal Glands • Sit on top of the kidneys • Separated into the cortex (outer region) and the medulla (inner region)
  • 3. Adrenal Cortex 1. Mineralocorticoids (Aldosterone): Regulate blood volume and composition by conserving sodium ions and eliminating potassium ions.
  • 4. Adrenal Cortex 1. Mineralocorticoids (Aldosterone): Regulate blood volume and composition by conserving sodium ions and eliminating potassium ions. 2. Glucocorticoids (Cortisol and Hydrocortisone): Increase glucose levels in the blood by increasing protein and fat metabolism and stimulating release of glucose from liver. Antiinflammatory.
  • 5. Adrenal Cortex 1. Mineralocorticoids (Aldosterone): Regulate blood volume and composition by conserving sodium ions and eliminating potassium ions. 2. Glucocorticoids (Cortisol and Hydrocortisone): Increase glucose levels in the blood by increasing protein and fat metabolism and stimulating release of glucose from liver. Anti-inflammatory. 3. Gonadocorticoids (Androgens and Estrogens): Cause development of secondary sex characteristics. Makes very small amounts compared to that produced by gonads.
  • 6. Drawing (pg 9) • Draw Adrenal gland
  • 7. Adrenal medulla • Develops from neural tissue and is stimulated by neurons
  • 8. Adrenal medulla • Develops from neural tissue and is stimulated by neurons • Produces epinephrine (adrenaline) and norepinephrine (noradrenaline): Cause fight or flight response-increased heart rate, blood pressure, and breathing rate, diverts blood away from digestive organs and to skeletal muscle
  • 9. Pancreas • Contains over 1 million pancreatic islets (islets of Langerhans) that consist of endocrine cells
  • 10. Pancreas • Contains over 1 million pancreatic islets (islets of Langerhans) that consist of endocrine cells • The islets are surrounded by exocrine cells, which produce digestive enzymes
  • 11. Pancreas • Contains over 1 million pancreatic islets (islets of Langerhans) that consist of endocrine cells • The islets are surrounded by exocrine cells, which produce digestive enzymes • Islets contain alpha and beta cells
  • 12. Pancreas • Contains over 1 million pancreatic islets (islets of Langerhans) that consist of endocrine cells • The islets are surrounded by exocrine cells, which produce digestive enzymes • Islets contain alpha and beta cells • Alpha cells produce glucagon, which raises blood sugar by stimulating the liver to break down glycogen and release glucose into the bloodstream
  • 13. Pancreas • Contains over 1 million pancreatic islets (islets of Langerhans) that consist of endocrine cells • The islets are surrounded by exocrine cells, which produce digestive enzymes • Islets contain alpha and beta cells • Alpha cells produce glucagon, which raises blood sugar by stimulating the liver to break down glycogen and release glucose into the bloodstream • Beta cells produce insulin, which lowers blood sugar by stimulating body cells to transport glucose out of the blood and into the cells
  • 14. Pineal Gland • Tiny gland in the brain • Produces melatonin, which causes sleepiness. Melatonin production increases in response to darkness.
  • 15. Thymus • Located behind the sternum • Large in children, shrinks throughout adulthood • Produces thymosin, which is essential to development of T-lymphocytes, a type of white blood cell in the immune system
  • 16. Gonads • Ovaries produce estrogen and progesterone, which control the menstrual cycle and cause development of secondary female sex characteristics • Testes produce testosterone, which causes development of male secondary sex characteristics
  • 17. Placenta • Site of exchange between mother and baby during pregnancy
  • 18. Placenta • Site of exchange between mother and baby during pregnancy • Also produces hormones that maintain pregnancy 1. Human chorionic gonadotropin: causes uterine lining to not be shed. Used in pregnancy tests
  • 19. Placenta • Site of exchange between mother and baby during pregnancy • Also produces hormones that maintain pregnancy 1. Human chorionic gonadotropin: causes uterine lining to not be shed. Used in pregnancy tests 2. Human placental lactogen: prepares breasts for lactation
  • 20. Placenta • Site of exchange between mother and baby during pregnancy • Also produces hormones that maintain pregnancy 1. Human chorionic gonadotropin: causes uterine lining to not be shed. Used in pregnancy tests 2. Human placental lactogen: prepares breasts for lactation 3. Relaxin: causes pelvic ligaments to relax and become more flexible
