Posterior
Oxytocin: causes contractions of the smooth muscle in the wall of the uterus.
(ADH) antidiuretic hormone: regulates water balance and affects portions of the kidneys called the collecting tubules, this conserves the water for the body.
Thyroid gland: Produces thyroxine and calcitonin
Thyroxin
Causes cells of the body to have a higher rate of metabolism.
Calcitonin
Lowers blood calcium levels by signaling bones to increase calcium absorption and signaling the kidneys to excrete more calcium.
Parathyroid gland
Parathyroid hormone
Increases blood calcium levels by stimulating the bones to release calcium, kidneys to to reabsorb more calcium, and the intestines to absorb more calcium from food.
Pancreas: Produces insulin and glucagon
Insulin
Lowers blood glucose levels by promoting the uptake of glucose by most cells of the body to make a glycogen.
Glucagon
Raises blood glucose levels by stimulating liver cells to convert glycogen to glucose and release the glucose into the blood.
Adrenal gland: Produces cortisol and aldosterone
Aldosterone
Affects the kidneys and is important for reabsorbing sodium.
Cortisol
It increases blood glucose levels and reduces inflammation.
Testis(male): Produces testosterone
Ovary(female): Produces estrogen
Is composed of glands and functions as a communication system.
Hormones
Steroid
Are composed of lipids that can easily pass through the plasma membrane because they are soluble in lipids, and they bind to receptors inside the cell.
Nonsteroid ( Amino acid)
Are composed of lipids that can easily pass through the plasma membrane because they are soluble in lipids, and they bind to receptors inside the cell.
Negative feedback
The endocrine system plays an important role in sustaining and regulating homeostasis using negative feedback mechanisms.
