The endocrine system produces hormones that work to control and regulate many different body processes. The endocrine system coordinates with the nervous system to control the functions of other organ systems. Cells of the endocrine system produce molecular signals called hormones. These cells may make up endocrine glands, may be tissues, or may be found in organs or tissues that have functions other than hormone production. Hormones circulate throughout the body and stimulate a response in cells that have receptors capable of binding to them. Changes made to the host cells affect the function of the organ system to which they belong. Many of the hormones are secreted in response to signals from the nervous system, so the two systems work in concert to bring about changes in the body.
hormones
Maintaining homeostasis within the body requires the coordination of many different systems and organs. A mechanism for communication between neighboring cells, and between cells and tissues in distant parts of the body, occurs through the release of chemicals called hormones. Hormones are released into body fluids, usually the blood, which carries them to their target cells where they cause a response. Hormone-secreting cells are often found in specific organs, called endocrine glands, and the cells, tissues, and organs that secrete hormones make up the endocrine system. Examples of endocrine organs include the pancreas, which produces the hormones insulin and glucagon to regulate blood glucose levels, the adrenal glands, which produce hormones such as epinephrine and norepinephrine that regulate stress responses, and the thyroid gland, which produces thyroid hormones. regulate metabolic rates.
Endocrine glands are different from exocrine glands. Exocrine glands secrete chemicals through ducts that lead out of the gland (not into the blood). For example, sweat produced by sweat glands is released into ducts that carry the sweat to the surface of the skin. The pancreas has both endocrine and exocrine functions because in addition to releasing hormones into the blood. It also produces digestive juices, which are transported through ducts to the small intestine.
CURRENT CAREER: Endocrinologist
An endocrinologist is a doctor who specializes in the treatment of endocrine disorders. An endocrinologist specializes in the surgical treatment of endocrine diseases and glands. Some of the diseases treated by endocrinologists include disorders of the pancreas (diabetes mellitus), disorders of the pituitary gland (gigantism, acromegaly, and pituitary dwarfism), disorders of the thyroid gland (goiter and Graves' disease), and disorders of the adrenal glands (Cushing's disease and Addison's disease ).
Endocrinologists are required to evaluate patients and diagnose endocrine disorders through extensive use of laboratory tests. Many endocrine diseases are diagnosed using tests that stimulate or suppress the function of endocrine organs. Blood samples are then taken to determine the effect of stimulating or suppressing an endocrine organ on hormone production. For example, to diagnose diabetes mellitus, patients must fast for 12 to 24 hours. They are then given a sugary drink, which stimulates the pancreas to produce insulin to lower blood glucose levels. A blood sample is taken one to two hours after consuming the sugary drink. If the pancreas is working properly, blood glucose levels will be within a normal range. Another example is the A1C test, which can be performed during a blood test. The A1C test measures average blood glucose levels over the past two to three months. The A1C test is an indicator of how well your blood glucose is being managed over a long period of time.
Once a disease like diabetes is diagnosed, endocrinologists can prescribe lifestyle changes and medications to treat the disease. Some cases of diabetes mellitus can be managed with exercise, weight loss and a healthy diet. In other cases, drugs may be required to enhance the production or effect of insulin. If the disease cannot be controlled by these means, the endocrinologist may prescribe insulin injections.
In addition to clinical practice, endocrinologists may also be involved in primary research and development activities. For example, ongoing islet transplantation research is investigating how healthy pancreatic islet cells can be transplanted into diabetic patients. Successful islet transplants may allow patients to stop taking insulin injections.
How do hormones work?
Hormones cause changes in target cells by binding to specific cell surface or intracellular hormone receptors, molecules embedded in the cell membrane or floating in the cytoplasm with a binding site that matches a binding site on the hormone molecule. That way, even though hormones circulate throughout the body and come into contact with many different types of cells, they only affect cells that have the necessary receptors. Receptors for a particular hormone may be found in or on many different cells, or may be restricted to a small number of specialized cells. For example, thyroid hormones act on many different types of tissues, stimulating metabolic activity throughout the body. Cells can have multiple receptors for the same hormone, but often also have receptors for different types of hormones. The number of receptors that respond to a hormone determines the sensitivity of the cell to that hormone and the resulting cellular response. In addition, the number of receptors available to respond to a hormone can change over time, resulting in increased or decreased cellular sensitivity. In upregulation, the number of receptors increases in response to increasing hormone levels, making the cell more sensitive to the hormone and allowing more cellular activity. When the number of receptors decreases in response to increasing hormone levels, called down-regulation, cellular activity decreases.
Endocrine glands
Endocrine glands secrete hormones into the surrounding interstitial fluid. These hormones are then diffused into the blood and transported to various organs and tissues within the body. Endocrine glands include the pituitary, thyroid, parathyroid, adrenal glands, gonads, pineal gland, and pancreas.
The pituitary gland, sometimes called the hypophysis, is located at the base of the brain (Figure \(\PageIndex{1}\)one). It is attached to the hypothalamus. The posterior lobe stores and releases oxytocin and antidiuretic hormone produced by the hypothalamus. The anterior lobe responds to hormones produced by the hypothalamus by producing its own hormones, most of which regulate other hormone-producing glands.
The anterior pituitary gland produces six hormones: growth hormone, prolactin, thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, and luteinizing hormone. Growth hormone stimulates cellular activities such as protein synthesis that promote growth. Prolactin stimulates milk production from the mammary glands. The other hormones produced by the anterior pituitary regulate the production of hormones by other endocrine tissues (Table \(\PageIndex{1}\)). The posterior pituitary gland is significantly different in structure from the anterior pituitary gland. It is a part of the brain, extending down from the hypothalamus, and contains mainly nerve fibers that extend from the hypothalamus to the posterior pituitary gland.
The thyroid gland is located in the neck, just below the larynx and in front of the trachea (Figure \(\PageIndex{1}\)si). It is a butterfly-shaped gland with two lobes that are connected to each other. Thyroid follicle cells synthesize the hormone thyroxine, also known as T4because it contains four iodine atoms and triiodothyronine, also known as T3because it contains three iodine atoms. T3and T4are released by the thyroid in response to thyroid-stimulating hormone produced by the anterior pituitary gland and T3and T4have the effect of stimulating metabolic activity in the body and increasing energy use. A third hormone, calcitonin, is also produced by the thyroid. Calcitonin is released in response to rising concentrations of calcium ions in the blood and results in a decrease in these levels.
Most people have four parathyroid glands. However, the number can vary from two to six. These glands are located on the posterior surface of the thyroid gland (Figure \(\PageIndex{1}\)si).
The parathyroid glands produce parathyroid hormone. Parathyroid hormone increases blood calcium concentrations when calcium ion levels fall below normal.
The adrenal glands are located on top of each kidney (Figure \(\PageIndex{1}\)do). The adrenal glands consist of an outer adrenal cortex and an inner adrenal medulla. These areas secrete different hormones.
The adrenal cortex produces mineralocorticoids, glucocorticoids and androgens. The main mineralocorticoid is aldosterone, which regulates ion concentration in urine, sweat and saliva. The release of aldosterone from the adrenal cortex is stimulated by a decrease in blood sodium ion concentrations, blood volume or blood pressure, or by an increase in blood potassium levels. Glucocorticoids maintain proper blood glucose levels between meals. They also control the stress response by increasing the synthesis of glucose from fat and protein and interact with epinephrine to cause vasoconstriction. Androgens are sex hormones produced in small amounts by the adrenal cortex. They normally do not affect sexual characteristics and may supplement the sex hormones released by the gonads. The adrenal medulla contains two types of secretory cells: one that produces epinephrine (adrenaline) and another that produces norepinephrine (noradrenaline). Epinephrine and norepinephrine cause immediate, short-term changes in response to stressors, causing the so-called fight-or-flight response. Responses include increased heart rate, breathing rate, heart muscle contractions, and blood glucose levels. They also speed up the breakdown of glucose in skeletal muscle and stored fat in adipose tissue and redirect blood flow to skeletal muscle and away from the skin and viscera. The release of epinephrine and norepinephrine is stimulated by nerve impulses from the sympathetic nervous system originating in the hypothalamus.
The pancreas is an elongated organ located between the stomach and the proximal part of the small intestine (Figure \(\PageIndex{1}\)Hey). It contains both exocrine cells that secrete digestive enzymes and endocrine cells that release hormones.
The endocrine cells of the pancreas form clusters called pancreatic islets or islets of Langerhans. Among the cell types in each pancreatic islet are alpha cells, which produce the hormone glucagon, and beta cells, which produce the hormone insulin. These hormones regulate blood glucose levels. Alpha cells release glucagon as blood glucose levels fall. When blood glucose levels rise, beta cells release insulin. Glucagon causes the liver to release glucose into the blood, and insulin facilitates the uptake of glucose by the body's cells.
The gonads—male testicles and female ovaries—produce steroid hormones. The testes produce androgens, with testosterone being the most important, which allow the development of secondary sex characteristics and the production of sperm. The ovaries produce estrogen and progesterone, which cause secondary sex characteristics, regulate egg production, control pregnancy, and prepare the body for childbirth.
There are many organs whose primary functions are non-endocrine but also possess endocrine functions. These include the heart, kidneys, intestines, thymus gland and adipose tissue. The heart has endocrine cells in the walls of the atria that release a hormone in response to increased blood volume. It causes a decrease in blood volume and blood pressure and decreases Na concentration+in the blood.
The gastrointestinal tract produces several hormones that aid in digestion. Endocrine cells are found in the lining of the gastrointestinal tract throughout the stomach and small intestine. They trigger the release of gastric juices, which help break down and digest food in the gastrointestinal tract.
The kidneys also have an endocrine function. Two of these hormones regulate ion concentrations and blood volume or pressure. Erythropoietin (EPO) is released by the kidneys in response to low oxygen levels. EPO triggers the formation of red blood cells in the bone marrow. EPO has been used by athletes to improve performance. But EPO doping has its risks, as it thickens the blood and increases the pressure on the heart. It also increases the risk of blood clots and therefore heart attacks and strokes.
The thymus gland is located behind the sternum. The thymus produces hormones called thymosins, which help develop the immune response in infants. Adipose tissue, or adipose tissue, produces the hormone leptin in response to food intake. Leptin causes a feeling of satiety after eating, reducing the desire for further food.

Regulation of Hormone Production
Hormone production and release is primarily controlled by negative feedback, as described in the discussion of homeostasis. In this way, the concentration of hormones in the blood is kept within a narrow range. For example, the anterior pituitary signals the thyroid to release thyroid hormones. Increasing blood levels of these hormones then feedback to the hypothalamus and anterior pituitary to inhibit further signaling to the thyroid gland (Figure \(\PageIndex{2}\)).

Unit Summary
Hormones cause cellular changes by binding to receptors on or within target cells. The number of receptors on a target cell can increase or decrease in response to hormonal activity.
Hormone levels are controlled primarily through negative feedback, in which increasing levels of a hormone inhibits its further release.
The pituitary gland is located at the base of the brain. The anterior pituitary receives signals from the hypothalamus and produces six hormones. The posterior pituitary gland is an extension of the brain and releases hormones (antidiuretic hormone and oxytocin) produced by the hypothalamus. The thyroid gland is located in the neck and consists of two lobes. The thyroid gland produces the hormones thyroxine and triiodothyronine. The thyroid also produces calcitonin. The parathyroid glands are located on the back surface of the thyroid gland and produce parathyroid hormone.
The adrenal glands are located on top of the kidneys and consist of the adrenal cortex and the adrenal medulla. The adrenal cortex produces corticosteroids, glucocorticoids and mineralocorticoids. The adrenal medulla is the inner part of the adrenal gland and produces epinephrine and norepinephrine.
The pancreas is located in the abdomen between the stomach and the small intestine. Clusters of endocrine cells in the pancreas form the islets of Langerhans, which contain alpha cells that release glucagon and beta cells that release insulin. Some organs have endocrine activity as a secondary function but have another primary function. The heart produces the hormone atrial natriuretic peptide, which works to reduce blood volume, pressure, and Na+concentration. The gastrointestinal tract produces various hormones that aid in digestion. The kidneys produce erythropoietin. The thymus gland produces hormones that help develop the immune system. The gonads produce steroid hormones, including testosterone in men and estrogen and progesterone in women. Adipose tissue produces leptin, which promotes satiety signals to the brain.
