  1. Maintaining Homeostasis

  2. What is Homeostasis?

  3. Temperature Control • Ectotherm • Behavioral control • Location change • Hibernate/estivate • Endotherm • Dispelling heat • Panting • Sweating • Staying warm • Shivering • Fat/hair • Location change • Hibernate/estivate/migrate

  4. Osmotic Control • Contractile vacuole • Urine Production

  5. Feedback Mechanisms • Feedback inhibition • Product or result of process stops process • Ex. Dog hot -> pants-> cools down -> stops panting

  6. Hormone Control • Hormones • Target Cell

  7. Human Endocrine System

  8. Pituitary Gland • Thyroid Stimulating Hormone (TSH) • Control metabolism • Growth Hormone • Causes bone and muscle growth • Prolactin • Milk production

  9. Pituitary Gland • Luteinizing Hormone (LH) • Menstrual cycle • Causes testosterone production in males • Follicle Stimulating Hormone (FSH) • Menstrual cycle • Sperm production

  10. Parathyroid Gland • Parathyroid hormone • Maintains proper Ca+ levels in blood

  11. Pancreas • Hormones • Insulin • Glucagon

  12. Adrenal Gland • Noradrenaline and Adrenaline • Causes increase in HR, BP, blood sugar, blood flow, and vessel dilation

  13. Gonads • Androgens • Develops and maintains male reproductive system • Determines gender • Estrogens • Develops and maintains female reproductive system • Progestins • Prepares uterus for fetus
