How does the endocrine system work step by step?
Your endocrine system continuously monitors the amount of hormones in your blood. Hormones deliver their messages by locking into the cells they target so they can relay the message. The pituitary gland senses when your hormone levels rise, and tells other glands to stop producing and releasing hormones.

Why is the endocrine system important?
Various processes in the endocrine system help to regulate the secretion of hormones and the resulting actions. This is essential for the body to maintain control over the action of the hormones. In other words, regulation is required to allow a hormone to initiate the intended reaction when needed and bring it to an end once the action has been completed.
What is the endocrine system?
By Yolanda Smith, B.Pharm. The endocrine system is made up of certain special glands and the hormones produced by those glands in the body. The hormones are important for instructing specific cells to produce particular actions in response to a stimulus or imbalance in the body. The glands are responsible to recognize the need for hormone secretion.
Why are glands important?
The glands are responsible to recognize the need for hormone secretion. The hormones travel in the bloodstream to the cells where they act, and bind to the cells to initiate their effects. These processes are tightly regulated by the endocrine system to maintain metabolic balance in the body. They are essential to keeping body functions normal.

How many adrenal glands are there?
There are two adrenal glands, each of which lies above a kidney. The adrenal glands have two distinct parts: the cortex (outer layer), which secretes steroid hormones, and the medulla (inner part), which secretes epinephrine and norepinephrine. There are more than 30 steroid hormones produced by the adrenal glands.
Why are endocrine glands called ductless glands?
Endocrine glands are also called ductless glands, because they secrete hormones directly into the bloodstream. In contrast, exocrine glands release their secretions through ducts (for example, the sweat glands produce fluid that flows to the skin's surface through tiny tubelike sweat ducts). Hormones can be considered chemical messengers.
