  4. 4. The Functions <ul><li>Thyroid Gland- Takes iodine in foods and turns it into thyroid Hormones </li></ul><ul><li>Thymus- Destroys abnormal cells </li></ul><ul><li>Adrenal Glands- works with the hypothalamus and pituitary gland. </li></ul><ul><li>Ovaries- Contains egg cells necessary for reproduction </li></ul><ul><li>Testicles- Produces testosterone and sperm </li></ul>
  5. 5. How Hormones Work <ul><li>Hormones are chemical messengers that travel throughout the body making processes </li></ul><ul><ul><li>Growth </li></ul></ul><ul><ul><li>Metabolism </li></ul></ul><ul><ul><li>Fertility </li></ul></ul><ul><li>Alters with Behavior </li></ul><ul><li>Makes your body change </li></ul><ul><ul><li>Especially during puberty </li></ul></ul>
  6. 6. Negative Feedback Loop <ul><li>The negative feedback loop in the endocrine system prevents the system from becoming overactive. </li></ul>
  7. 7. Blood Glucose Level <ul><li>The body uses blood sugar levels using two mechanisms: </li></ul><ul><ul><li>Hunger </li></ul></ul><ul><ul><li>Insulin </li></ul></ul><ul><li>Body forms glucose when it breaks foods that a person eats </li></ul><ul><li>Then turns into a usable form of energy </li></ul><ul><li>Glucose is a main energy source for the body </li></ul><ul><li>Measuring the amount of blood glucose in the blood helps evaluate: </li></ul><ul><ul><li>How the body breaks foods down into energy </li></ul></ul><ul><ul><li>How the liver is working </li></ul></ul><ul><ul><li>How the organs in the body help regulate blood glucose </li></ul></ul>
  8. 8. Diseases <ul><li>Crushing Syndrome- A lot of glucocorticoid hormones in the body </li></ul><ul><li>Type 1 Diabetes - When the pancreas fails to produce enough insulin </li></ul>
  9. 9. Vocabulary <ul><li>Hormone- Substance produced by a tissue and carried by the bloodstream to effect growth or metabolism </li></ul><ul><li>Thyroid gland- Two-lobed gland </li></ul><ul><li>Adrenal gland- Either of tow small glands, located above each kidney </li></ul><ul><li>Pancreas- A long irregularly shaped gland </li></ul><ul><li>Pineal glands- Small cone shaped organs in the brain. </li></ul><ul><li>Parathyroid gland- Small kidney shaped glands that lie in pairs </li></ul><ul><li>Thymus- Small glandular organ behind the breast bone </li></ul>
  10. 10. Vocabulary <ul><li>Testis- Together with the scrotum </li></ul><ul><li>Ovary- The female reproductive organ that produces ova </li></ul><ul><li>Pituitary gland- a small oval endocrine gland attached to the vertebrate brain </li></ul><ul><li>Hypothalamus- Part of the brain that regulates temperature </li></ul><ul><li>Epinephrine- An adrenal hormone that constricts blood vessels </li></ul><ul><li>Insulin-a pancreatic hormone that regulates metabolism of carbohydrates and fats </li></ul><ul><li>Glucagons- a pancreatic hormone that raises blood sugar levels </li></ul>
  11. 11. Vocabulary <ul><li>Homeostasis- the ability of an organism of cells </li></ul><ul><li>Norepinephrine- mediates chemical communication in the sympathetic nervous system </li></ul><ul><li>Growth Hormone- A growth hormone that you go through during puberty </li></ul>
