Learn certain things about this system


Endocrine Glands and Hormones. The endocrine system is made up of a network of glands. These glands secrete hormones to regulate many bodily functions, including growth and metabolism. Endocrine diseases are common and usually occur when glands produce an incorrect amount of hormones.


For an organism to function normally and effectively, it is necessary that the biochemical processes of its tissues operate smoothly and conjointly in a stable setting. The endocrine system provides an essential mechanism called homeostasis that integrates body activities and at the same time ensures that the composition of the body fluids bathing the constituent cells remains constant.

Negative Feedback

Negative Feedback is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. An example is Human body temperature - The hypothalamus of a human responds to temperature fluctuations and responds accordingly. If the temperature drops, the body shivers to bring up the temperature and if it is too warm, the body will sweat to cool down due to evaporation.

Type I Diabetes and Type II Diabetes

Type 1: Normally, the body's immune system fights off foreign invaders like viruses or bacteria. But for unknown reasons, in people with type 1 diabetes, the immune system attacks various cells in the body. Symptoms of type 1 diabetes usually develop quickly, over a few days to weeks, and are caused by blood sugar levels rising above the normal range (hyperglycemia). Type 1 diabetes requires lifelong treatment to keep blood sugar levels within a target range.

Type 2: Type 2 diabetes, once called non-insulin dependent diabetes, is the most common form of diabetes, affecting 90% to 95% of the 26 million Americans with diabetes. Type 2 diabetes can cause serious health complications. That's why is very important to know how to spot type 2 diabetes symptoms. Type 2 diabetes prevention is possible by adopting some healthy lifestyle habits and paying attention to specific preventable diabetes complications associated with this disease. Increasingly, weight loss surgery is being used as a tool to manage type 2 diabetes. That's because controlling diabetes and managing the related health risks is directly related to losing weight.
