processes or changes in hormone levels.
What regulates hormones? - answer✔1. Chemicals
2. Endocrine factors
3. Nueral control

What is the main function of the thyroid? - answer✔Production, storage, and release of thyroid
hormones T3 & T4, and calcitonin. Iodine is necessary for the production of these hormones.
When is calcitonin released? - answer✔When calcium levels are high. Inhibits reabsorption of
calcium but doesn't play a critical role.
when is T3 and T4 released? - answer✔Released in response to TSH from the anterior pituitary
stimulation.
What does the parathyroid gland release? and what does it do? - answer✔Parathyroid hormone-
regulates calcium levels by increasing reabsorption of calcium into the bones and kidneys when
calcium is low.
what does the adrenal cortex release? - answer✔cortisol and aldosterone
Cortisol - answer✔corticosteroid that regulates blood glucose, has anti-inflammatory effects.
Main hormone that responds to stress, released to help manage stressful environments.
Aldosterone - answer✔A mineralcortocoid produced by the adrenal cortex that promotes sodium
and water reabsorption by the kidneys and potassium excretion in urine.
What does the adrenal medulla secrete? - answer✔secretes epinephrine and norepinephrine
What does the pancreas secrete? - answer✔insulin, glucagon, somatostatin, and pancreatic
polypeptide
Insulin - answer✔produced by beta cells in pancreas; main regulator of metabolism and storage
of carbs, fats, and proteins in the cells.
What does insulin do? - answer✔stimulated by high blood glucose levels to makes the liver
convert glucose into glycogen. This causes blood glucose levels to decrease.
Glucagon - answer✔stimulated by decreased glucose levels in blood to increase blood glucose.
Given to patients with hypoglycememea to increase BG levels.
Somatostatin - answer✔secreted by delta cells in response to food intake, inhibits insulin
secretion glucagon and pancreatic polypeptide.
pancreatic polypeptide - answer✔released in response to hypoglycemia and protein rich foods,
inhibits gallbladder contractions & exocrine pancreas secretion.
what are the main organs responsible for glucose uptake? - answer✔Liver, muscles, & adipose
tissues.
