Day 6

  1. 1.  Responsible in regulating physiological processes and adjustments in metabolism, fluid balance, growth and reproduction. › Works closely with the Nervous System.  The study of the Endocrine System is called Endocrinology.
  2. 2. Hormones – chemical messengers produced and secreted by endocrine glands responsible for the regulation of body processes. They stimulate specific tissues to do processes.
  3. 3.  Fatty acid derivatives Steroid hormones Amino acid derivatives Peptide hormones
  4. 4. › Some hormones enter the cell and activate genes› Many hormones act by signal transduction
  5. 5.  Epinephrin – causes adrenaline rush Angiotensin – causes vasoconstriction Angiotensinogen – causes vasoconstriction Calcitonin – reduces blood Ca2+ Cholecystokinin – release of bile and digestive enzymes from the pancreas
  6. 6.  Gastrin – stimulates the release of gastric juices Ghrelin – stimulates appetite Glucagon – increases blood glucose Growth Hormone – stimulates growth and cell production Insulin – lowers blood glucose
  7. 7.  Leptin – lowers appetite, increases metabolism Orexin – stimulates awakeness Parathyroid hormone – increases blood Ca2+ Testosterone – libido, increase in muscle mass and strength
  8. 8.  Responsible for defending the body from foreign materials that cause diseases, called pathogens. › Immunology is the study of the Immune System. › Vertebrates are special because they have WBCs that are specialized in carrying out immune responses.
  9. 9.  Antigens – causes the production of the antibodies Antibodies – identifies and neutralizes foreign materials like bacteria or viruses
  10. 10.  Lysozyme Cytokines Interferons Macrophages Interleukins Phagocytes
  11. 11.  Body’s response to pathogen invasion or physical injury. › Mast cells › Edema, or swelling › fever
  12. 12.  Antibody-mediated Cell-mediated
  13. 13.  Phagocytes › Neutrophils › macrophages Lymphocytes › T cells › B cells › NK cells
  14. 14.  A very complicated process involving antibodies. Takes two to three days to discuss. We’ll skip this.
  15. 15.  Active immunity Passive immunity
  16. 16.  Asexual Sexual
  17. 17.  Budding Fragmentation Parthenogenesis
  18. 18.  Internal Fertilization Hermaphroditism
  19. 19.  Sperm Scrotum Epididymis Vas deferens Ejaculatory duct Seminal Vesicles Bulbourethral gland Penis
  20. 20.  Egg Follicle Oviduct Uterus Endometrium Vagina
