Endocrine System

thyroid stimulating hormone (TSH)

TSH stimulates the thyroid gland to release thyroid hormones, controls the thyroid's activity and hormone release

secreted by the anterior pituitary gland

function of T3/T4

regulate metabolism, oxygen use, nutrient processing, protein synthesis, and growth

increase the body's sensitivity to certain chemicals called catecholamines

secreted by the thyroid gland

function of growth hormone (GH)

promotes growth by helping build proteins and tissues

supports overall body growth and cell reproduction

secreted by the anterior pituitary gland

function of antidiuretic hormone (ADH)

controls water balance by making the kidneys reabsorb water, which reduces urine output

secreted by posterior pituitary gland

function of adrenocorticotropic hormone (ACTH)

stimulates the adrenal cortex to make corticosteroid hormones like cortisol

secreted by the anterior pituitary gland

function of insulin

Insulin lowers blood sugar by helping cells absorb glucose

secreted by the beta cells of the pancreas

function of glucagon

raises blood sugar by signaling the liver to release stored glucose

secreted by the alpha cells of the pancreas

function of parathyroid hormone (PTH)

increases blood calcium levels by releasing calcium from bones and increasing calcium absorption in the intestines and kidneys

secreted by the parathyroid gland

function of calcitonin

lowers blood calcium levels by helping bones absorb calcium and reducing calcium release from bones

secreted by the thyroid gland
