Endocrine system includes…
 Pituitary Gland
 Adrenal Gland
 Thyroid Gland
 Hypothalamus
 Pancreas
 Thymus
Its function is to…
 Control many of the body’s activities as well as long-
term changes.
Structure info:
 Pituitary Gland ●
 controls many body activities
 Adrenal Gland ●
 produces the hormone
adrenaline that triggers the
body to respond to emergency
situations
 Thyroid Gland ●
 Controls the release of
energy from food
 Hypothalamus ●
 part of the brain that
links the nervous
system to the endocrine
system
Structure info:
 Pancreas ●
 produces the hormones
insulin and glucagon that
control the level of glucose in
the blood.
 Thymus ●
 controls the development of
cells in the immune system.
How is structure and function
related?
 The glands in conjunction
with the nervous system
release hormones that
control the body’s activities
and changes.
Taking care…
 Excessive drug use, such
as steroids, can alter the
chemical/hormone
release in the body
causing unwanted
changes
 Eat balanced diet and
drink plenty of water
 Exercise regularly
Diseases/Conditions of the
Endocrine
system:
 Hyperthyroidism and
Hypothyroidism - Thyroid hormones
regulate how the body breaks down
food and either uses that energy
immediately or stores it for the
future. In other words, our thyroid
hormones regulate our body's
metabolism. Hypo=low metabolism
/Hyper=high metabolism

 Diabetes - occurs when the pancreas,
a gland behind the stomach, does not
produce enough of the hormone
insulin. Insulin is necessary to carry
sugar from the bloodstream into the
cells.
Facts…
 When a hormone enters the
bloodstream, it does not affect
any other cell other than the
one it was sent out for, the
target cell. The chemical
structure of the hormone and
target cell fit together like
puzzle pieces.
 The pituitary gland is about the
size of a pea.
