Functions of the Endocrine System

Human Physiology pp Cite as. The biological role of the endocrine system is closely linked to that of the nervous system; the two together coordinate the functions of the other in some cases widely separated organs and organ systems. The distinguishing feature of the endocrine system is that its influence is exerted by way of a number of substances, the hormones. Chemically, the hormones are a nonuniform group; the range of compounds represented includes steroids, amino-acid derivatives, peptides and proteins. They have specific actions on these target organs, actions that as a rule cannot be produced by any other substance.

Your endocrine system is made up of several organs called glands. The glands, located all over your body, create and secrete release hormones. Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, skin, muscles and other tissues. These signals tell your body what to do and when to do it. Hormones deliver their messages by locking into the cells they are targeting so they can relay the message.

Endocrine Community. Email Print Discuss. Written by Robert M. Sargis MD, PhD. Simply put, the endocrine system is a network of glands that secrete chemicals called hormones to help your body function properly. Hormones are chemical signals that coordinate a range of bodily functions. The endocrine system works to regulate certain internal processes.

Functions of the Endocrine System

Human endocrine system , group of ductless glands that regulate body processes by secreting chemical substances called hormones. Hormones act on nearby tissues or are carried in the bloodstream to act on specific target organs and distant tissues. Diseases of the endocrine system can result from the oversecretion or undersecretion of hormones or from the inability of target organs or tissues to respond to hormones effectively. It is important to distinguish between an endocrine gland, which discharges hormones into the bloodstream, and an exocrine gland , which secretes substances through a duct opening in a gland onto an external or internal body surface. Salivary glands and sweat glands are examples of exocrine glands. Both saliva, secreted by the salivary glands, and sweat, secreted by the sweat glands, act on local tissues near the duct openings.


The endocrine system helps to regulate a variety of bodily functions through the secretion of hormones. Learn about the organs that make up the endocrine.


Endocrine glands and their hormones

Communication is a process in which a sender transmits signals to one or more receivers to control and coordinate actions. Together, these two systems are primarily responsible for maintaining homeostasis in the body. The nervous system uses two types of intercellular communication—electrical and chemical signaling—either by the direct action of an electrical potential, or in the latter case, through the action of chemical neurotransmitters such as serotonin or norepinephrine. Neurotransmitters act locally and rapidly. When an electrical signal in the form of an action potential arrives at the synaptic terminal, they diffuse across the synaptic cleft the gap between a sending neuron and a receiving neuron or muscle cell.

The endocrine system is a network of glands and organs located throughout the body. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones.

 Ну… - задумалась Сьюзан.  - Это зависит от оперативности, с которой ARA пересылает почту.

An Overview of the Endocrine System

 Дэвид, прости. Он увидел пятна света. Сначала слабые, еле видимые на сплошном сером фоне, они становились все ярче.

Я позвоню и все объясню. Мне в самом деле пора идти, они связи, обещаю. - Дэвид! - крикнула.  - Что… Но было уже поздно. Дэвид положил трубку.

Они потеряли веру. Они стали параноиками. Они внезапно стали видеть врага в. И мы, те, кто близко к сердцу принимает интересы страны, оказались вынужденными бороться за наше право служить своей стране. Мы больше не миротворцы. Мы слухачи, стукачи, нарушители прав человека.  - Стратмор шумно вздохнул.
