What gland controls the endocrine system - necessaryThe endocrine glands are those which release their secretions inside the blood. The blood carries substances throughout the body until it reaches its target organ. The exocrine glands are the glands that release their secretions directly into the target organ or tissue. There are some things that our body needs in large amounts to function. Conversely, some substances drive the show by being present only in small quantities. One of such substances is a hormone.
What gland controls the endocrine system - thatThe medial region, called the isthmus, is flanked by wing-shaped left and right lobes. Each of the thyroid lobes has a pair of parathyroid glands embedded on its posterior surface. The tissue of the thyroid gland is composed mostly of thyroid follicles lined with simple cuboidal epithelium. The follicles are made up of a central cavity filled with a sticky fluid called colloid. Surrounded by a wall of epithelial follicle cells, the colloid is the center of thyroid hormone production, and that production is dependent on the essential and unique component of thyroid hormones: iodine. Thyroglobulin is the precursor to two thyroid hormones: triiodothyronine T 3 with three iodines and thyroxine T 4 with four iodines. Thyroglobulin is produced by the follicle cells and secreted into the colloid where the iodines are attached to form T 3 and T 4. Ninety-nine percent of circulating T 3 and T 4 is bound to specialized transport proteins called thyroxine-binding globulins TBGs , to albumin, or to other plasma proteins.

Endocrine System Organs
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. It is responsible for regulating a range of bodily functions through the release of hormones. Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues http://rectoria.unal.edu.co/uploads/tx_felogin/puritan-writers-the-wonders-of-the-invisible/cultureforpeopleblogspotcom.php to do or how to function.
