The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.
Explanation:
The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.
Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.
Some examples of bodily functions that are controlled by the endocrine system include:
metabolism
growth and development
sexual function and reproduction
heart rate
blood pressure
appetite
sleeping and waking cycles
body temperature
Endocrine system organs
The endocrine system is made up of a complex network of glands, which are organs that secrete substances.
The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.
The glands of the endocrine system include:
- Energy
