Endocrine System Created by: Michael Marbry

Function of the system.

The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.

Homeostasis and its role in the endocrine system.

Homeostasis - a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group.


Role: Homeostasis plays a big role in this system. It keep the temperature regulated. If your body gets to hot then homeostasis will trigger that negative feedback to start sweating and let out some of that heat.

Negative feedback

Negative eedback - Negative feedback is a process that happens when your systems need to slow down or completely stop a process that is happening.


An example of negative feedback is the regulation of the blood calcium level. The parathyroid glands secrete parathyroid hormone, which regulates the blood calcium amount. If calcium decreases, the parathyroid glands sense the decrease and secrete more parathyroid hormone. The parathyroid hormone stimulates calcium release from the bones and increases the calcium uptake into the bloodstream from the collecting tubules in the kidneys. Conversely, if blood calcium increases too much, the parathyroid glands reduce parathyroid hormone production

Type 1 & 2 Diabetes

Type 1 Diabetes - Type 1 diabetes is an autoimmune disease in which a person’s pancreas stops producing insulin, a hormone that enables people to get energy from food. It occurs when the body’s immune system attacks and destroys the insulin-producing cells in the pancreas, called beta cells.


Symptoms: Increased thirst, Frequent urination, Bedwetting in children who previously didn't wet the bed during the night, Extreme hunger, Unintended weight loss, Irritability and other mood changes, Fatigue and weakness, Blurred vision, In females, a vaginal yeast infection


Common: Type 1 diabetes is usually diagnosed in children and young adults, and was previously known as juvenile diabetes. Only 5% of people with diabetes have this form of the disease.


Treatment: Taking insulin, Carbohydrate counting, Frequent blood sugar monitoring, Eating healthy foods, Exercising regularly and maintaining a healthy weight


Type 2 Diabetes: This is when the bodies of people with type 2 diabetes make insulin. But either their pancreas does not make enough insulin or the body cannot use the insulin well enough.


Symptoms: Increased thirst, Increased hunger (especially after eating), Dry mouth, Nausea and sometimes vomiting. Increased urination, Fatigue (weak, tired feeling), Blurred vision, Numbness or tingling of the hands or feet.


Common: In 2012, 29.1 million Americans, or 9.3% of the population, had diabetes.


Treatment: Healthy eating, Regular exercise, Possibly, diabetes medication or insulin therapy, Blood sugar monitoring
