What are endocrine glands?

endocrine glands are tissues that secrete substances called hormones into the bloodstream. These glands are located in several places in the body and exclude hormones that affect the huge range of body functions and processes. Endocrine glands include hypothalamus, pituitary gland, adrenal glands, parathyroid, pineal, thyroid, Langerhans, ovaries and testicles. The uterine and placenta of pregnant women are also considered part of the endocrine system. Examples of such functions include metabolism, cell growth and puberty. On the other hand, the nervous system controls functions that occur rapidly, such as movement. The nervous system and the endocrine system have different overall functions, but they are not quite different systems and cooperate in mutual connection with the aim of regulating body processes. These two systems are connected by a part of the brain called Hypothalamus.

endocrine glands affect the way the body works by the production of hormones. These molecules act as messengers who say different types of cells that dMake it and when they have it. There are many types of hormones, but most cell types can only interact with a limited number. Each endocrine gland produces several specific hormones and, if necessary, excludes them in response to hormonal signals produced by other endocrine glands.

The most important of the endocrine glands is the pituitary gland. He considered the "main gland" of the endocrine system, excluding hormones that regulate thyroid activity, ovaries, testicles and adrenal gland. The pituitary also produces hormones that control body tissue growth, initiate uterine contractions during delivery and lactation in breastfeeding women, regulate the ability of the body to feel pain and help body leveling of water levels. The pineal is also a pineal gland. This gland excludes melatonin, which participates in the regulation of the cycle of sleep and waking.

The

endocrine glands of the thyroid gland and body semi -throat, which are found in the throat, regulate metabolism and calcium. ShieldThe end of the gland produces hormones that control the pace at which cells burn fat and other energy for energy, as well as the pace of other chemical reactions in the body. The parathyroid glands produce a hormone that controls calcium levels available in the bloodstream.

Adrenal glands, found at the top of the kidneys, produce two important types of hormones: epinephrine and corticosteroids. Epinephrine or adrenaline is produced in response to stress and results in an increase in blood pressure and heart rate. Corticosteroids are important in several body processes, including stress reaction, immune function and sexual function.

In the pancreas, two important hormones are produced: glucagon and insulin. These hormones regulate Blood D levels, energy levels and converting sugar or stored energy into usable energy to fuel cell chemical reactions. Both hormones are produced in the abdominal area called Langerhans.

Sex hormones are produced by two endocrine glands: testiclesIn men and ovaries in women. In men, the testes of androgens, such as testosterone and body change that occur during puberty as well as sperm production. In women, ovaries produce estrogen and progesterone hormones, control the development of the body during puberty and also control the menstrual cycle.
