2. Endocrine GlandsEndocrine Glands
A gland that secretes a substance (a
hormone) into the bloodstream. The
endocrine glands are "glands of
internal secretion." They include the
hypothalamus, pituitary gland, pineal
gland, thyroid, parathyroid glands,
heart which makes atrial-natriuretic
peptide, the stomach and intestines,
islets of Langerhans in the pancreas,
the adrenal glands, the kidney which
makes renin, and calcitriol, fat cells .
the testes, the ovarian follicle and the
corpus luteum in the ovary.
3. PancreasPancreas
The pancreas is a long flattened
gland located deep in the belly
abdomen. Because the pancreas
isn’t seen or felt in our day to day
lives, most people don't know as
much about the pancreas as they
do about other parts of their
bodies. The pancreas is, however,
a vital part of the digestive
system and a critical controller of
blood sugar levels.
4. TestisTestis
The male sex gland, located
behind the penis in a pouch of
skin called the scrotum. The
testes produce and store sperm
and are also the body's main
source of male hormones, such
as testosterone. These hormones
control the development of the
reproductive organs and other
male characteristics, such as
body and facial hair, low voice,
and wide shoulders. Also known
as testicle.
5. OvariesOvaries
The female gonad, one of a pair of
reproductive glands in women. The ovaries
are located in the pelvis, one on each side
of the uterus. Each ovary is about the size
and shape of an almond. The ovaries
produce eggs (ova) and female hormones.
During each monthly menstrual cycle, an
egg is released from one ovary. The egg
travels from the ovary through a fallopian
tube to the uterus. The ovaries are the
main source of female hormones, which
control the development of female body
characteristics, such as the breasts, body
shape, and body hair. They also regulate
the menstrual cycle.
6. AdrenalAdrenal
A small gland located on
top of the kidney. The
adrenal glands produce
hormones that help control
heart rate, blood pressure,
the way the body uses
food, the levels of
minerals such as sodium
and potassium in the blood,
and other functions
particularly involved in
stress reactions.
7. Pituitary GlandPituitary Gland
The main endocrine gland.
It is a small structure in
the head. It is called the
master gland because it
produces hormones that
control other glands and
many body functions
including growth. The
pituitary consists of the
anterior and posterior
pituitary.
8. ThyroidThyroid
A gland that makes and stores
hormones that help regulate
the heart rate, blood pressure,
body temperature, and the
rate at which food is converted
into energy. Thyroid hormones
are essential for the function
of every cell in the body. They
help regulate growth and the
rate of chemical reactions
metabolism in the body.
Thyroid hormones also help
children grow and develop.
