The endocrine system creates and releases hormones that transport to various parts of the body to control the body's reactions to things like stress, pain, growth and nutrient intake. These hormones can be thought of as messengers that give directions to different parts of the body, allowing the body to react to changes and maintain homeostasis.Continue Reading
The endocrine system is made up of the many glands in the body. These include the thyroid and parathyroid glands, the pituitary gland, the pancreas, adrenal glands and testicles in men and ovaries in women. The glands synthesize and send out hormones, and each hormone targets a specific organ or type of tissue.
When glands create hormones, they get transported through either the bloodstream or the lymph. Hormones help the body to act or react to any threat to homeostasis. Hormones aid throughout reproduction and birth. They help people sleep and wake up. The adrenal glands give off adrenaline to help a person perform in potential danger, and they release dopamine linked with the body's reward system. In general, the endocrine system plays a major role in helping the body maintain homeostasis because it gives off the messengers to help the body to react to any threats to homeostasis.Learn more about Human Anatomy

The body parts are grouped into several systems, including the nervous system of the brain, spinal cord and nerves that control the body, its muscles and glands; and the skeletal system of the bones and joints that support body structure, create blood cells and store minerals. Other systems include the cardiovascular, respiratory, digestive and reproductive systems.Full Answer >
Peristalsis is a series of contractions that pushes solids or liquids through tubes in certain parts of the body, primarily the digestive system. Peristalsis is basically a wave of contractions, such as those used by the esophagus and small intestines to move food through the system.Full Answer >
Better Medicine states that hunger is the result of a complicated group of interactions controlled by the body's endocrine, digestive and neurological systems. These systems send chemicals to the brain to indicate both hunger and fullness. When a person consistently experiences excessive hunger, it can be a sign of illness.Full Answer >
