- Organs of the endocrine system. Endocrine glands tend to be vascular and do not have ducts. Ducts are instead found in exocrine glands, which produce hormonal signals outside of the body.
- Hypothalamus. Borders. The hypothalamus is an almond-sized structure in the limbic system of the brain, and the endocrine system’s control center. Its borders are the following
- Pituitary gland. Location. The pituitary gland (hypophysis cerebri) is a pea-sized, ovoid shaped structure attached via the infundibulum to the tuber cinereum of hypothalamus.
- Pineal gland. Location. Along with the hypothalamus and pituitary gland, the pineal gland (epiphysis cerebri) is found in the brain. It is a small organ located in a depression between the superior colliculi, inferiorly to the splenium of the corpus callosum.
Hormones regulate internal functions from metabolism and growth to sexual development and the induction of birth. They circulate through the bloodstream, bind to target cells, and adjust the function of whole tissues and organs. It all starts with the hypothalamus and the pituitary gland, the masters of the endocrine system.

Your endocrine system is in charge of creating and releasing hormones to maintain countless bodily functions. Endocrine tissues include your pituitary gland, thyroid, pancreas and others. There are several conditions related to endocrine system issues — usually due to a hormone imbalance or problems directly affecting the tissue.

What is the function of the endocrine system?
The main function of your endocrine system is to release hormones into your blood while continuously monitoring the levels. Hormones deliver their messages by locking into the cells they target so they can relay the message. You have more than 50 different hormones, and they affect nearly all aspects of your health — directly or indirectly. Some examples include: Metabolism. Homeostasis (constant internal balance), such as blood pressure and blood sugar regulation, fluid (water) and electrolyte balance and body temperature. Growth and development. Sexual function. Reproduction. Sleep-wake cycle. Mood. Very small amounts of hormones can trigger significant responses and changes in your body. If your body has too little or too much of a hormone, it affects your health. This often causes noticeable symptoms.
What are the endocrine system organs?
Your endocrine system consists of three types of tissues: Endocrine glands. Organs. Endocrine-related tissues.
What are endocrine system diseases?
There are hundreds of conditions related to issues with your endocrine system. Hormonal imbalances make up a significant number of endocrine diseases. This typically means there’s too much or not enough of one or more hormones. But issues directly affecting endocrine system glands and organs, like benign and cancerous tumors, also account for endocrine diseases. The below groupings cover some — but certainly not all — endocrine system-related conditions. Diabetes and metabolic conditions: Type 1 diabetes. Type 2 diabetes. Gestational diabetes Metabolic syndrome. Obesity. Endocrine cancers and tumors: Adrenal tumors. Neuroendocrine tumors. Pancreatic cancer. Parathyroid cancer. Parathyroid tumors. Pituitary tumors. Thyroid cancer. Thyroid disease: Hypothyroidism and hyperthyroidism. Thyroiditis. Thyroid nodule. Sexual development, function and reproduction conditions: Amenorrhea (absent periods). Erectile dysfunction. Growth hormone deficiency and excess (acromegaly or gigantism). Hormonal acne. Hormone-related infertility. Hypogonadism. Menopausal disorders. Polycystic ovary syndrome (PCOS). Premenstrual syndrome (PMS). Calcium and bone conditions: Hypercalcemia and hypocalcemia. Osteopenia and osteoporosis. Vitamin D deficiency.
What healthcare providers treat endocrine system issues?
An endocrinologist is a healthcare provider who specializes in the endocrine system and conditions related to your hormones. They can diagnose endocrine conditions, develop treatment and management plans, and prescribe medication. Pediatric endocrinologists specialize in conditions that affect children under 18. Some endocrine conditions may require more than one provider. For example, care for cancer affecting endocrine tissues would also involve oncologists and other cancer specialists. Advertisement
How can I keep my endocrine system healthy?
It’s not possible to prevent all types of endocrine system-related conditions, like those that have autoimmune causes. But there are some steps you can take to try and keep your endocrine system healthy, including: Maintaining a weight that’s healthy for you. Exercising regularly. Getting proper nutrition. Getting quality sleep. Limiting or avoiding alcohol. Avoiding or quitting smoking. Chemicals called endocrine disrupters can also affect your endocrine system. These chemicals are in many everyday products, including some: Cosmetics. Food and beverage packaging. Toys. Carpets. Pesticides. You can’t completely avoid contact with endocrine-disrupting chemicals (EDCs). But you can make informed choices to reduce your exposure to them and your risk of any potential health effects. Lastly, if you have a family history of endocrine system-related conditions, like diabetes or thyroid disease, talk to your healthcare provider. They can help you understand your risk of developing the condition and let you know what symptoms to look out for. A note from Cleveland Clinic Your endocrine system is vital to your existence. While normally, your body carefully balances its hormones, having too little or too much of a certain hormone can lead to health problems. If you’re experiencing any concerning symptoms, it’s important to talk to your healthcare provider. They’re available to help.

Oct 10, 2024 · Moreover, adipose tissue has long been known to produce hormones, and recent research has revealed that even bone tissue has endocrine functions. Figure 15.2.1 15.2. 1: Endocrine System. Endocrine glands and cells are located throughout the body and play an important role in homeostasis.
The endocrine system uses hormones to control and coordinate your body's internal metabolism (or homeostasis) energy level, reproduction, growth and development, and response to injury, stress, and environmental factors.

How does the endocrine system work?
Endocrine Controls. The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body (target site). In essence, hormones serve as messengers, controlling and coordinating activities throughout the body. (See also Endocrine Glands.)
