Endocrine System

Body Systems


The endocrine system is a collection of glands that produce hormones that regulate metabolism, growth and development, reproduction, sleep and mood.


Homeostasis is the ability to maintain internal stability in an organism while environmental changes. In the endocrine system the mechanism homeostasis is provided that brings together body activities and at the same time assure the composition of the body fluids bathing the constituent cells remains constant.

Negative Feedback mechanism

These mechanism change the variable back to it original value. A good example of a negative feedback mechanism is the control of blood sugar by insulin. When blood sugar rises, receptors in the body sense change. As a result the pancreas secretes insulin into the blood effectively lowering blood sugar levels. When blood sugar level is homeostasis, pancreas stops releasing insulin.

Type I Diabetes

Type I diabetes develops mostly in young people, however it can develop in adults. In type I diabetes your body no longer makes or enough insulin because the body's immune system, which protects you from infections by getting rid of bacteria or viruses, attacked and destroyed the cells that make insulin. Some symptoms are excessive thirst, increased urination, weight loss, tiredness, nauseam and blurred vision. Prevalence is about 1.25 million American children and adults have type I diabetes. There are many options of treatments like; getting injections of insulin, taking medication, healthy diet, being physically active, controlling your blood pressure level and cholesterol level.

Type II Diabetes

Type II diabetes mostly affects middle-aged and older people. People who are overweight and inactive are also more likely to develop type II diabetes. Usually begins with insulin resistance, condition that occurs fat, and muscle do not use insulin to carry glucose into the body's cells to use energy. Resulting of this the body needs more insulin to help glucose into cells. The pancreas makes more insulin, over time the pancreas doesn't make enough insulin when blood sugar levels increase. A couple signs of type II diabetes are dry mouth, increased urination, weight loss or gain, tiredness, and blurred vision. 1.7 million new cases of type II diabetes were diagnoses in Americans in 2012. Treatments are using diabetes medicines, healthy diet, being physically active, controlling your blood pressure level and cholesterol level.
