How does the Endocrine system work? The function of the endocrine system is to regulate body activities, similar to the nervous system in that they both regulate body activities. The difference is that the nervous system uses electrical messengers to send signals to the body, and the endocrine system uses chemical messengers “hormones” to make the changes to effect changes within the body. The endocrine system work together with the nervous system to help control body function and regulations, including metabolism, nutrition, elimination, temperature, fluid and electrolyte balance, growth, and reproduction. The endocrine system in our body consists of a number of glands which make, store, and release chemicals. There are a large number of endocrine glands in the human…show more content…
Key components of the Endocrine System The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroid, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system. Hypothalamus gland is located in the brain. The function of the hypothalamus is to regulate production of hormones in the anterior pituitary gland. Hypothalamus produces “releasing and “inhibitory” hormones. Pituitary gland located just below the brain secretes a number of hormones. One of the hormones secreted by this gland is human growth hormone, which controls the growth of the human body. It helps control the development of the bones and muscles in the body, which explains why there are short people “dwarf” and tall people “giant”. When the body does not produce enough GH the person remains short. On the other hand, when the body produces too much GH the person becomes very tall. Thyroid gland is in the anterior neck, directly below the crioid cartilage. Thyroid gland makes a hormone called thyroxin. The function of thyroxine hormone is
