  • Human Physiology is the science of body
    functions
  • Human Anatomy is the study of body
    structures
  • Homeostasis works off:
    negative feedback
  • Eating because you are overweight is what kind of feedback
    positive feedback
  • structure and function

    mirror one another
  • Homeostasis works off:
    negative feedback
  • Not a feedback loop
    getting sleepy; sleepiness does not change how bright it is outside. no feedback
  • eating because you're overweight
    positive feedback
  • gaining interest on a bank account
    positive feedback
  • speeding up to close the gap between you & the car in front of you
    negative feedback
  • steroid hormones are most chemically similar to
    lipids
  • water soluble hormones are most chemically similar to
    proteins
  • distance is an important factor for
    paracrine hormones.
    - they move through interstitial fluids to get to nearby cells. also, the farther the distance, the weaker the signal (like a TV signal)
  • anterior pituitary releases hormones under the effect of
    releasing hormones
  • steroid hormones are able to freely pass through ____ so they work ____
    cell membranes; inside the cell
  • endocrine hormones travel through the ____ and signal cells that have ____
    bloodstream; receptors
  • T/F: after a large meal, insulin will be elevated
    true
    - due to high blood glucose levels
  • ACTH will trigger cortisol from the
    a) adrenal medulla
    b) adrenal cortex
    b) adrenal cortex
  • Portal system carries blood to organs (or other parts of body) before going to the ____
    heart
  • T/F: tropic hormones stimulate other glands
    true
    - a lot are released by the anterior pituitary
  • PTH ____ affects blood calcium by amount absorbed in digestion
    a) directly
    b) indirectly
    b) indirectly
  • PTH ____ affects blood calcium through kidneys & bone
    a) directly
    b) indirectly
    a) directly
  • aldosterone is released by the
    adrenal cortex
  • T/F: one function of hormones is to release electrolytes
    false
  • Stimulates mammary gland development
    prolactin
  • stimulates adrenal cortex to release cortisol
    ACTH
  • Inhibits thyroid stimulating hormone (TSH)
    thyroid hormones
  • T/F: iodine is used by the thyroid

    true
  • which hormone stimulates the gonads
    LH
    - FSH could also be an answer
  • which hormones affect blood sugar
    cortisol & glucagon
    - insulin could also be an answer
  • GAS
    resistance due to prolonged cortisol, leading to exhaustion
  • which hormone is elevated in dealing with long term stress
    cortisol
  • gland that releases hormones in response to high blood calcium
    thyroid
    - calcitonin
  • gland that releases hormones in response to low blood calcium
    parathyroid
    - PTH
  • calcitonin affects calcium directly in what way
    net amount deposited in bone
  • gland that responds to darkness
    pineal gland
    - biological clock
  • which zone of the adrenal cortex secretes cortisol
    fasciculata
    - glucocorticoids
    - middle layer
  • which zone of the adrenal cortex secretes androgens
    reticularis
    - deepest layer
  • which zone of the adrenal cortex secretes mineralcorticoids
    glomerulosa
    - most superficial layer
  • aldosterone is produced DIRECTLY in response to
    high potassium levels
    - aldosterone is not directly triggered by RAAS system, low blood sugar triggers the RAAS system to release renin from kidneys, that acts on angiotensinogen to create angiotensin I, then ACE in lungs creates angiotensin II, that triggers adrenal gland to release aldosterone
