The human body is one of the most difficult structures on the face of the earth, because it contains devices that work all the time regularly and harmony so that the human being in the best case, all the devices in the human body work in an integrated, and each device completes the work of other devices, Our bodies are the musculoskeletal system, the nervous system, the digestive system, the circulatory system, and the most important organs that regulate the work of the remaining devices is the endocrine system.
Endocrine system
Is a device located within the human body, consisting of a large number of glands, so that each gland of these gland secretion of its own hormone, and move this hormone through the blood to the rest of the body cells, and characterized the glands in this device that secrete hormones directly in the blood Without the need for channels and therefore called endocrine, unlike the external glands that secrete their hormones through channels.
The endocrine glands of the endocrine system
Each gland of the endocrine function is important in the human body, and these glands are:
