Endocrine System

Is a network of glands and organs located throughout the body. It’s similar to the nervous system in that it plays a vital role in controlling and regulating many of the body’s functions. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones.

Functions of the Endocrine System

The Functions of the Endocrine System 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

The Organs & Glands of the Endocrine System

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:  Hypothalamus. While some people don’t consider it a gland, the hypothalamus produces multiple hormones that control the pituitary gland. It’s also involved in regulating many functions, including sleep-wake cycles, body temperature, and appetite. It can also regulate the function of other endocrine glands.  Pituitary.  The pituitary gland is located below the hypothalamus. The hormones it produces affect growth and reproduction. They can also control the function of other endocrine glands.  Pineal.  This gland is found in the middle of your brain. It’s important for your sleep-wake cycles.  Thyroid.  The thyroid gland is located in the front part of your neck. It’s very important for metabolism.  Parathyroid. Also located in the front of your neck. The parathyroid gland is important for maintaining control of calcium levels in your bones and blood.  Thymus.  Located in the upper torso. The thymus is active until puberty and Produces hormones important for the development of a type of white blood cell called a T cell.  Adrenal.  One adrenal gland can be found on top of each kidney. These glands produce hormones important for regulating functions such as blood pressure, heart rate, and stress response.  Pancreas.  The pancreas is located in your abdomen behind your stomach. Its endocrine function involves controlling blood sugar levels. Some endocrine glands also have non-endocrine functions. For example, the ovaries and testes produce hormones, but they also have the non-endocrine function of producing eggs and sperm, respectively.
