Endocrine Glands and Hormones

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.

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. In contrast, the hormones secreted by endocrine glands are carried by the circulation to exert their actions on tissues remote from the site of their secretion.

Но вот туфли - совсем другое. Даже во время учебы в колледже она старалась покупать самую лучшую обувь. Нельзя дотянуться до звезд, если чувствуешь себя ущемленной, - сказала как-то ее тетушка.  - И если уж попала туда, куда стремилась, постарайся выглядеть на все сто. Сьюзан сладко потянулась и взялась за. Она загрузила программу Следопыт и, приготовившись отправиться на охоту, взглянула на адрес электронной почты, который вручил ей Стратмор.
