
Located in the brain, the hypothalamus is
responsible for certain metabolic processes and
activities of the Autonomic Nervous System,
such as temperature, hunger, thirst, fatigue, etc.
It links the Endocrine System with the Nervous
System by using the pituitary gland.

The thymus gland secretes hormones that
enhance the immune system. It is located in the
throat and attached to the heart and thyroid

Pancreas- oblong flattened gland that produces many important
hormones such as insulin
Located between the stomach and the spine; partially located
behind the stomach, the rest is located in the curve of the small
intestine
For a more visual approach touch your pinky and your right
thumb together, keep the other three fingers straight and together.
Then place your hand in the center of your tummy (with your
three fingers pointing left) and your hand will be approximately at
pancreas level.

Adrenal glands- split into two parts, the cortex
(outside) and the medulla (inside). The cortex
produces steroid hormones such as
testosterone, and the medulla produces
epinephrine, also known as adrenaline.
Shaped like triangles and are located on top
of the kidneys


produces a hormone called melatonin that
helps the testes and ovaries to develop. It also
changes messages from the nervous system
into endocrine signals.
Shockingly, it is only about 1 centimeter long!

Part of the male reproductive system, the testes
produce sperm over the entire course of a
male’s lifetime.


The pituitary gland is a pea-sized gland located
at the base of the skull between the optic
nerves.
The pituitary gland secretes hormones.

The thyroid gland is located in the front of the neck, below the
larynx (voice box).
The small, two-inch gland consists of two lobes, one on each side

The thyroid plays an important role in regulating the body's
metabolism and calcium balance.
