hormones that the adrenal gland produces

As parathyroid hormone increases blood calcium levels, calcium levels eventually return to normal. The parathyroid gland secretes parathyroid hormone in response to low blood calcium levels. Negative feedback is demonstrated in the regulation of blood calcium. Once the response eliminates the initial stimulus, the pathway is halted. In negative feedback, an initial stimulus provokes a response that works to reduce the stimulus. They can be regulated by other hormones, by glands and organs, by peripheral nervous system neurons, and by negative feedback mechanisms. These organs include the heart, liver, and kidneys.Įndocrine system hormones are regulated in several ways. There are also other organs in the body that have secondary endocrine functions.

The major glands of the endocrine system are the pineal gland, pituitary gland, thyroid, and parathyroid glands, adrenal glands, pancreas, thymus, ovaries, and testes. These systems help to maintain a constant internal environment in response to environmental changes. Both the endocrine system and the nervous system are responsible for maintaining homeostasis in the body. Hormones control various cellular activities including growth development reproduction energy use and storage and water and electrolyte balance. Only cells with specific receptors for a certain hormone will be influenced by that hormone. Once in the blood, the hormones travel through the cardiovascular system until they reach their target cells. These glands secrete hormones into the blood. This system is comprised of several major endocrine glands.

The endocrine system regulates vital processes in the body including growth, metabolism, and sexual development.
