What Is The Primary Function Of Hormones – Hormones are the body’s chemical messengers. They help tissues and organs do their jobs by traveling through the bloodstream. There are several types of hormones that act on different aspects of body function. Let’s look at the important hormones and their functions.
Hormones are secreted in the body by several glands, which are necessary for growth, development, reproduction, etc. These are chemical substances that coordinate the activities of living organisms as well as their growth. They are secreted by special tissues of our body through the endocrine glands. Different hormones have different effects on body shape. Some of these hormones act quickly, starting or stopping the process, and some will work continuously for a long period of time to carry out their functions. They help in growth, development, metabolism, sexual function, reproduction, etc. What happens to the body when these hormones are released in greater or lesser quantities. This article discusses a list of important hormones necessary for the functions of our body. List of important hormones and their functions. 1. Thyroid Hormones The thyroid gland mainly secretes two hormones, triiodothyronine (T3) and thyroxine (T4), which help control the metabolism in our body. Additionally, these hormones regulate weight, energy levels, core body temperature, skin, hair, etc. 2. Insulin Source: www.thumbs.dreamstime.com This hormone is produced by the pancreas, a leaf-shaped gland located in the abdominal cavity. behind the stomach. This allows the body to use glucose or sugar from carbohydrates in food for energy or store glucose for future use. This helps keep your blood sugar levels from being too high, i.e. hyperglycemia, or too low, i.e. hypoglycemia. 3. Estrogen. This is a female sex hormone produced by the ovaries. It is responsible for reproduction, menstruation and menopause. Excess estrogen in a woman’s body increases the risk of breast cancer, uterine cancer, depression, moodiness, etc. If the level of estrogen in a woman’s body is lower, then it leads to acne, skin lesions, thinning skin, hair loss, etc. 4. Progesterone The hormone progesterone is produced in the ovaries, placenta during pregnancy and the adrenal glands. It stimulates and regulates various functions. It plays an important role in maintaining pregnancy. It helps the body prepare for conception, pregnancy and regulates the monthly cycle. If pregnancy does not occur, progesterone levels drop and the menstrual cycle begins. It also plays a role in sexual desire. Composition and functions of blood 5. Prolactin This hormone is secreted by the Pituitary Gland after childbirth during lactation, which allows a woman to breastfeed. Levels of the hormone prolactin increase during pregnancy, meaning it also plays an important role in fertility by inhibiting follicle-stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH). 6. Testosterone Source: www.amazonaws.com This is the male sex hormone. It is an anabolic steroid in nature and helps build muscle in the body. In men, it plays an important role in the development of male reproductive tissues; testicles and prostate. It also promotes the development of secondary sexual characteristics such as increase in muscle and bone mass, growth of body hair, etc. If not enough testosterone is secreted in men, it can lead to abnormalities including weakness and bone loss. 7. Serotonin. It is a mood-boosting hormone, also known as a natural feel-good chemical. It is associated with learning and memory, sleep regulation, digestion, regulates mood, some muscle functions, etc. Due to an imbalance of serotonin in the body, the brain does not produce enough of the hormone to regulate mood or stress levels. Low level of serotonin causes depression, migraine, weight gain, insomnia, carbohydrate cravings, etc. Excessive level of serotonin in the body causes agitation, confusion stage, sedation, etc. 8. Cortisol Source: wwwi.pinimg.com This hormone is produced through the adrenal glands. It helps you stay healthy and energetic. Its main role is to control physical and psychological stress. When in danger, it increases heart rate, blood pressure, breathing, etc. During stressful times, the body releases cortisol to cope with the situation. High levels of cortisol consistently cause ulcers, high blood pressure, anxiety, high cholesterol, etc. Similarly, low levels of cortisol in the body cause alcoholism, a condition responsible for chronic fatigue syndrome, etc. 9. Adrenaline The adrenaline hormone is secreted in organism. the adrenal medulla, as well as some neurons of the central nervous system. It is also called the emergency hormone because it initiates a quick response that makes a person think and react quickly to stress. It increases the metabolic rate, dilates blood vessels leading to the heart and brain. During a stressful situation, adrenaline is quickly released into the blood and sends impulses to organs that cause a specific reaction. 10. Growth hormone. It is also known as growth hormone. It is essentially a protein hormone containing 190 amino acids that is synthesized and secreted by cells called somatotrophs in the anterior pituitary gland. It stimulates cell growth, cell reproduction, cell regeneration and accelerates metabolism. This is important in human development. So, now you may have learned about the various hormones and their functions in the human body. Various glands and hormones in the human body List of organs that help in digestion of the human body

AcceptPosterior pituitary hormones are released from the posterior pituitary gland, located at the base of the brain, and include two hormones: vasopressin (i.e., antidiuretic hormone) and oxytocin. The pituitary gland is a pea-sized organ that is called the master gland of the body because it secretes hormones that direct other glands and organs to release hormones throughout the body. Consequently, it controls the vital functions of the skin, brain, reproductive organs and vision.
The pituitary gland is divided into two lobes: anterior and posterior. The anterior pituitary gland makes up 80% of the pituitary gland and regulates growth, metabolism and reproduction through the production of various hormones, including human growth hormone (GH), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ATG), and follicle-stimulating hormone. stimulating hormone (FSH), luteinizing hormone (LH) and prolactin. The pituitary gland is connected to the hypothalamus by a stalk of blood vessels and nerves. The hypothalamus is a part of the brain that plays a vital role in connecting the endocrine and nervous systems by interacting with the pituitary gland to produce and secrete certain hormones for certain body functions. It communicates with the anterior pituitary gland through the release of hormones, whereas it communicates with the posterior pituitary gland through nerve impulses. This close connection is known as the hypothalamic-pituitary axis. Ultimately, the hypothalamus controls several body functions, including body temperature, thirst, appetite and weight control, sleep cycles, blood pressure and heart rate, and emotions.
The posterior lobe of the pituitary gland produces two hormones. This contrasts with the anterior pituitary gland, which produces six hormones.
Hormones produced by the posterior pituitary gland include vasopressin and oxytocin. Vasopressin is also called antidiuretic hormone (ADH) and acts on the kidneys to conserve water. It is also important for maintaining fluid and electrolyte balance in the body. The hypothalamus contains specialized osmoreceptors that maintain water homeostasis. Osmoreceptors are nerve cells that have the inherent ability to sense the amount of solutes, such as sodium or potassium, in the blood. When the body loses water (ie, through sweating during exercise, vomiting, diarrhea), dehydration may occur and plasma solute concentrations increase. Hypothalamic osmoreceptors then initiate the release of ADH from the posterior pituitary gland. ADH primarily acts on the kidneys, increasing the amount of water reabsorbed from the kidney filtrate back into the blood. The amount of urine released decreases and, consequently, the urine filtrate becomes more concentrated and darker in color. Increased water reabsorption helps counter increased solute concentrations in the blood.

A decrease in blood volume or blood pressure, such as during hypovolemic shock, may also promote the release of ADH. By promoting greater reabsorption of water in the kidneys, blood volume increases, thereby maintaining blood pressure during volume loss. ADH can also act as a vasopressor, or an agent that constricts blood vessels, further increasing and normalizing blood pressure. This action of ADH is particularly common in peripheral small arteries.
Decreased secretion of ADH by the posterior pituitary gland can lead to diabetes insipidus (DI), a condition associated with polyuria or frequent urination. This is because people with DC are unable to concentrate their urine and subsequently produce large amounts of urine every day, which can potentially lead to severe dehydration.
Another hormone secreted by the posterior pituitary gland is oxytocin. Oxytocin is primarily produced in the hypothalamus, from where it is either sent to the pituitary gland for storage and subsequent release into the blood, or sent to other parts of the brain and spinal cord.
