Hormones are the development of a person their growth; the ability to concentrate, aggressiveness, sexual drive, reproduction, metabolism and play a major role on the ability to learn and the type of mood a person is in.

The adrenal glands are right above the kidneys, each has two parts know as the adrenal medulla (inner core) and the adrenal cortex (outer layer) both are responsible for the body’s reaction to stress. According to Morris & Maisto it pours several hormones into the bloodstream, “epinephrine which activates the sympathetic nervous system and noepinephrine not only raises blood pressure by causing the blood vessels to become constricted, but also is carried by the bloodstream to the anterior pituitary and triggers the release of still more hormones” (pg. 67, 2010) hence prolonging the reaction to stress.
The pituitary gland located under the brain and is connected to the hypothalamus is known as the “master gland” releasing the largest number of hormones which in turn “has the widest range of effects on the body’s functions” (Morris & Maisto, pg. 66, 2010). It is responsible for the blood pressure, body growth, sexual...
