The Parts of the Endocrine System

Your endocrine system includes glands and hormones. Glands are groups of cells that make and give off hormones and other chemicals that your body needs to stay healthy. Special glands work within specific areas of your body to carry out certain functions. The endocrine system impacts just about every area of your body. This system even affects psychology because it helps regulate your moods.

About the Endocrine System

It’s hard to see the endocrine system as it works in your body, but you can see the results of its work. Often, you might not think much about the endocrine system unless it isn’t working correctly. If the endocrine system stops functioning properly, you might see issues with your growth, mood, metabolism, or digestion. The endocrine system works with the nervous system for many processes.

  • The Endocrine System: The endocrine system includes glands and hormones that control how cells function in the body.
  • Endocrine System: Facts, Functions, and Diseases: The hormones released by glands are in charge of regulating growth, metabolism, reproduction, sleep, mood, and tissue function.
  • Endocrine System: The nervous system is responsible for stimulating glands, which then produce the hormones needed by the body.
  • What Is the Endocrine System? Some of the glands that make up the endocrine system include the pituitary gland, the thyroid gland, the thymus gland, and the adrenal glands.
  • Anatomy of the Endocrine System: After glands secrete hormones, these chemicals are carried throughout the body in the bloodstream to the cells and organs that need them.

What the Endocrine System Does

Hormones are chemical messengers that travel throughout the body, giving instructions to cells so they know what to do. Hormones move through your bloodstream. Cells are programmed for the hormones that are in charge of them, so the hormones and cells know how to work together. Outside issues can affect how hormones function, such as infections and stress.

Parts of the Endocrine System

The endocrine system includes a number of glands that are located throughout the body. Some glands are located in the brain, while others are located in the neck and in the abdomen. These glands have specific jobs regulating different areas of your body.

The hypothalamus is a special group of cells that sit in the lower middle part of your brain, responsible for working with both the nervous system and the endocrine system. The pituitary gland sits under the hypothalamus, and it is about the size of a pea. The pituitary gland is in charge of other glands in this system.

The thyroid is in charge of setting the speed at which cells use fuel, while the parathyroids are in charge of how your body uses calcium. The adrenal glands are in charge of your body’s salt and water balance as well as your metabolism and your immune system. The melatonin secreted by the pineal gland helps your body know when to be awake and when to sleep. The gonads produce sex hormones in your body. And your pancreas produces insulin and glucagon, which work to make sure your body has the fuel it needs for energy.

  • The Hypothalamus: The hypothalamus is a part of the brain that produces hormones to regulate your temperature, hunger, thirst, mood, sleep, and more.
  • An Overview of the Hypothalamus: The hypothalamus is the connection between the nervous and endocrine systems, and it helps keep the internal balance of the body in check.
  • What Is the Pituitary Gland? The hypothalamus controls the pituitary gland, which is responsible for several other glands, such as the thyroid and the adrenals.
  • The Pituitary Gland: People sometimes call the pituitary gland the master gland because it is in charge of many other glands in the endocrine system.
  • Introduction to Parathyroid Glands: The parathyroid glands sit behind the thyroid gland, and they are responsible for controlling calcium levels in the body.
  • Thyroid and Parathyroid Glands: The thyroid gland is in the neck, and it produces thyroxine and triiodothyronine, which are hormones.
  • Adrenal Glands: The adrenal glands sit at the top of your kidneys, and they help make sure your metabolism and immune system function correctly.
  • What Are the Adrenal Glands? The adrenal glands also help with kidney function, and their name means “near the kidney” in Latin.
  • The Pancreas, Pineal Gland, and Gonads: The pineal gland is responsible for producing melatonin, which is an antioxidant and helps with your sleeping and eating cycles. Gonads produce sex hormones.
  • Overview of Endocrinology: The pineal gland is located in the brain. The gonads secrete testosterone and androsterone in males and estrogen and progesterone in females.
  • What Is the Pancreas? The pancreas is located in the abdomen, and it is involved in both digestion and regulating blood sugar.
  • The Pancreas and its Functions: The pancreas helps with changing the foods you eat into fuel for your body.
