Cards (22)

  • The endocrine system is composed of glands which secrete chemicals called hormones directly into the bloodstream.
  • label endie
    (if u cant figure out the 2nd word its probably gland)
    A) Pituitary gland
    B) thyroid
    C) pancreas
    D) adrenal glands
    E) ovary
    F) testicle
  • Blood glucose concentration is monitored and controlled by the pancreas.
  • If blood glucose levels are too high, the pancreas detects it and releases insulin.
  • Insulin acts in the liver to reduce blood glucose levels by:
    -increasing glucose absorption from blood into liver and muscle cells. --converting excess glucose into glycogen.
  • What is type 1 diabetes?
    It's a genetic disorder where the pancreas fails to produce sufficient insulin. This can cause uncontrolled high blood glucose levels. It can be treated with insulin injections.
  • What is type 2 diabetes?
    When body cells do not respond to insulin produced by the pancreas. A carbohydrate controlled diet and an exercise regime are common treatments.
  • What is a risk factor for type 2 diabetes?
    obesity
  • When blood glucose concentration is too low, the pancreas releases glucagon which converts glycogen back into glucose and released into the blood.
  • Pituitary gland: found at the base of the brian and is called the master gland. this is because the hormones secreted stimulate other endocrine glands.
  • The pancreas: secretes two hormones: insulin and glucagon.
  • Insulin causes blood sugar levels to decrease
  • Glucagon causes blood glucose levels to increase
  • The adrenal glands are found above the kidney
  • The adrenal glands secrete adrenaline
  • Adrenaline increases metabolic rate
  • The thyroid is found in the neck
  • The thyroid secretes thyroxine
  • The thyroid regulates basal metabolic rate
  • What is basal metabolic rate?
    The speed of chemical reactions in the body when it is resting
  • What are other functions of thyroxine?
    Stimulating protein synthesis- for growth and repair of cells
  • The thyroid is stimulated by TSH
