HOW THE ENDOCRINE SYSTEM
WORKS WELL WITH OTHERS
⦿
Placenta
Besides providing a connection between mother and child, the
placenta is a special endocrine organ. It produces hormones that
are similar to those produced in the body. Human estrogens, and
progesterone are among the most important of these because
they help maintain a normal pregnancy
⦿
Skin, Liver, and Kidneys
The skin, liver and kidneys work together to synthesize 1,25diydroxyvitamin D the active form of vitamin D, which helps
maintain normal levels of calcium and phosphorus in the blood.
In the skin, a molecule made from cholesterol is converted to
vitamin D by exposure to ultraviolet rays from the sun. Vitamin D
undergoes further chemical changes, first in the liver and then in
the kidneys, to become calcitriol. Calcitriol acts on the intestine,
kidneys, and bones to maintain normal levels of blood calcium
and phosphorus.
FUN FACTS
⦿
There are nearly 30 different hormones made in your
body. • Hormones made in the hypothalamus gland control
feelings of hunger and thirst. • The thyroid gland controls how much energy and
stamina you have throughout the day. • The pineal gland releases melatonin, which is
responsible for controlling sleep-wake patterns. • Dwarfism is caused when there is not enough growth
hormone released from the pituitary gland during childhood. QUESTIONS
