The Functions of the Endocrine System
- Where the Nervous System is responsible for controlling faster bodily functions such as respiration, the Endocrine System controls gradual functions such as growth.
- It regulates not only the growth of tissues but also their functions.
- It sends messages through hormones to regulate everything from mood to reproduction to metabolism.
Glands are structures made of cells that remove materials from the blood, use those materials to produce hormones, and then release these chemicals into the body to perform specific functions. There are two kinds of glands: exocrine and endocrine glands. While exocrine glands, such as salivary glands, release secretions directly into the skin or mouth, endocrine glands release hormones directly into the bloodstream for transport.
