The Endocrine system
The body system that consists of gland that produce
hormones.
Gland – A group of cell that secretes hormones
Hormone – is a chemical messenger released into the
bloodstream
Hypothalamus
The hypothalamus is an area of the brain that produces
hormones that control:
Body temperature, Hunger, Moods, Release of hormones
from many glands, especially the pituitary gland, Sex drive,
Sleep, and Thirst
Pituitary gland
Master gland
It controls all other glands
It is located below the hypothalamus in the brain.
It is about the size of a pea
Thyroid Glad
Produces thyroxin. This is the thyroid gland.
This hormone (thyroxin) controls metabolism and calcium
balance in the body.
Metabolism is the rate at which food is converted into
energy
Parathyroid glands
These glands release hormones which control the amount
of calcium and phosphorus in the body.
There are four parathyroid glands.
They are about the size of a grain of rice.
Adrenal Glands
Adrenal glands are triangle-shaped glands located on top
of the kidneys
he inner part of the adrenal gland is called the medulla and
produces adrenaline and noradrenaline
Pancreas
A fish-shaped spongy grayish-pink organ about 6 inches (15
cm) long that stretches across the back of the abdomen,
behind the stomach. The head of the pancreas is on the
right side of the abdomen and is connected to the
duodenum (the first section of the small intestine). The
narrow end of the pancreas, called the tail, extends to the
left side of the body.
[1] to produce pancreatic endocrine hormones (eg, insulin
& glucagon), which help regulate many aspects of our
metabolism and [2] to produce pancreatic digestive
enzymes.
