Endocrine system of the body
The endocrine system is important for numerous differentfunctions in the human body as it affects almost every organ, tissue and cellinside it. It is of utmost importance for the regulation of the reproductiveprocesses, sexual function, metabolism, tissue function, development, growthand mood. The nervous system controls the faster processes such as the bodymovement and breathing, while the endocrine system takes care of all slowerprocesses. These systems usually need to cooperate so that the entire body canfunction properly. The essential parts of the endocrine system are differenttypes of glands and hormones. Glands are groups of cell which produce andsecrete different types of chemicals. Hormones are in charge of transferringinformation between the cells in the human body. Each type of hormone affectsonly certain types of cells. Some glands only secrete their chemicals inspecific areas of the body. The most important glands in the human body includereproductive glands, pineal body, adrenal glands, thyroid, parathyroids,pituitary gland and hypothalamus. The inner part of the adrenal gland isreferred to as the adrenal medulla and it is in charge of different types ofcatecholamines such as epinephrine. Epinephrine is also referred to asadrenaline and it is in charge of increasing the heart rate and blood pressureonce the body gets exposed to stress. The outer part of the adrenal gland iscalled the adrenal cortex and it is in charge of production of corticosteroids.These hormones are in charge of sexual function, sexual development, the immunesystem, metabolism, the body’s response to stress and a healthy balance ofwater and salt inside the body. The thyroid gland is located in the lower neck,more precisely in its front part. It looks like a butterfly and is in charge ofthe production of triiodothyronine and thyroxine, which are thyroid hormones. Theyare in charge of controlling the rate at which the cells burns fuels obtainedfrom food in order to produce precious energy. The release and the productionof these hormones is regulated by thyrothropin, which is a certain type ofhormone released by the pituitary gland. The thyroid hormones are also ofutmost importance in the normal growth and development of bones, the brain andthe nervous system. Parathyroids are four very small glands attached to themain thyroid gland and they function together. They are in charge of theproduction of the hormone called parathyroid. This hormone is of utmostimportance when it comes to regulating the levels of calcium in the blood. Oneof the most important glands in the human body is the pituitary gland. This glandis very small and can be found at the very base of the brain. Sometimes it isreferred to as the master gland. Different factors such as changes in theseasons or emotions may affect the production of the pituitary hormones. There aretwo main parts of the pituitary gland and those are the posterior lobe and the anteriorlobe. The posterior lobe is in charge of production of an antidiuretic hormoneand the oxytocin. These hormones are in charge of controlling the balance ofwater in the body and triggering the contractions of the uterus in a pregnantwoman. The anterior lobe of the pituitary gland is in charge of regulating thereproductive glands, the adrenal glands and the thyroid. It also producedseveral important hormones such as corticotrophin, thyrotropin, prolactin andthe growth hormone. Corticotropin is in charge of stimulating the adrenalglands, thyrotropin is in charge of stimulating the activity of the thyroidgland, prolactin is in charge of stimulating the milk production in pregnantwomen and the growth hormone is of utmost importance for the normal growth ofdifferent body tissues. The pituitary gland also produces endorphins. These typesof hormones are in charge of reducing the pain and acting on the nervous system.The master gland is also in charge of controlling the ovulation and themenstrual cycles of a woman and also of signaling the reproductive glands tomake sex hormones. The hypothalamus is a certain type of gland which can befound at the lower central part of the brain and it actually represents themain link between the nervous and the endocrine system. It contains certainnerve cells which are in charge of regulating the activity of the pituitarygland.
Function of the liver
The liver is the largest organ in the human body and it canalso be considered as a gland. This is due to the fact that it secretes bile.It weighs about 3.5 pounds and it measures about 6.5 inches vertically and 8inches horizontally. It is commonly 4.5 inches thick. It can be found in theupper right part of the abdomen, just under the diaphragm. The liver producesdifferent types of important proteins, deals with the fats, metabolizes andstores carbohydrates, secretes the bile, eliminates all potentially harmfulbiochemical products and detoxifies the body.
