The endocrine system is made of glands that regulate various body functions. The
System plays a very important part in maintaining growth, the reproductive process,
andthe way the body uses food. It also helps the body with stress and emergencies.
... .The glands in the endocrine system control body functions by creating hormones.
These molecules are set free into the blood, which delivers them through out the body.
The hormones are chemical messengers. When the hormones reach the tissues, its
effects spread throughout the body. An example is the hormone insulin which causes
cells throughout the body to take in and use sugar from the bloodstream.
...The chief endocrine glands include the adrenal glands, the pituitary gland, the
parathyroid glands, and the thyroid gland. Other endocrine glands include the ovary,
testes, thymus, and the pineal gland. The brain, the kidneys, the stomach, and the
pancreas also have endocrine tissues and produce hormones. The pituitary gland, which
is near the bottom of the brain, is often called the master gland. It releases a number
of hormones, which, in turn, regulate other endocrine glands. However, hormones
produced by the hypothalamus, which is a part of the brain, control the pituitary
grand itself. The hypothalamus connects the nervous and endocrine control
systems.
