The endocrine system is one of the most important systems Without it you would be an emotional‚ non-making baby‚ and out of your mind human. The endocrine system helps with maintaining homeostasis by regulation of the activity cells. The endocrine system is basically hormones and those hormones are released into the blood of the body controlled by stimulus. The endocrine system does not and can’t work alone. It works with many other systems every day. For example‚ it works with the nervous system

adrenal glands. It is also known as hypocortisolism or adrenal insufficiency. The disease occurs when your adrenal glands do not produce sufficient amounts of certain hormones. The adrenal glands do not produce enough cortisol and more often than not‚ insufficient amounts of aldosterone. Autoimmune disease can be attributed to approximately 70 percent of the cause for Addison’s disease. The autoimmune system mistakenly attacks the adrenal glands and kills the outer layer of the gland. Examples
