__**The Function**__

The function of the [|Endocrine System]  is to work with the Nervous System to maintain homeostasis (stable internal environment). Example- Normal body temperature. You sweat when you're hot to cool down your body. [|Homeostasis] (dynamic equilibrium) regulates your growth, development, other body hormones and feedback functions. Homeostasis is a balanced condition inside the body.

**__Glands-__**

There are six main glands in the body.[|Glands] A gland is a group of cells that produces and secretes, or gives off chemicals. A gland selects and removes material from the blood
 * Pituitary- The pituitary gland is located at the base of the brain. It is known as the "master gland" and controls growth and releases many different hormones to control other glands. It is most known for releasing the growth hormone which not only helps the muscle cells grow but also tissue and bone.
 * Adrenals- they make a fluid called adrenaline, which helps you through stress situations. The hormone is also referred to as the "Fight or Flight" hormone, preparing your body to fight or run away.
 * Thyroid- this gland controls how quick the body uses energy. This gland produces Thyroxine, which regulates the rate of metabolism, and helps control other systems.
 * Parathyroid's- These small glands (there are four) are located with the thyroid at the back of the neck. They secrete the parathyroid hormone.
 * Pancreas- The pancreas is also in the Digestive System as well as the Endocrine System . It produces both insulin, which controls the amount of glucose flow in the bloodstream.
 * Ovaries (Female)- These are the female endocrine glands. They produce estrogen and are also apart of the Reproductive System.
 * Testes (Male)- The testes mainly produce testosterone but also produce androgens. They are components in both the Endocrine and Reproductive Systems.

__**Hormones-**__
 * Estrogen - this is found in women and is produced in the ovaries
 * Pituitary Hormones- the pituitary gland produces nine different hormones that regulate the other systems in the body.
 * Testosterone - this hormone is found in men and is produced in the testes
 * HGH- (human growth hormone) stimulates growth and can be given to a shorter person, when recommended. Growth hormone is composed of 191 amino acids to form a single chain.
 * Adrenaline- Adrenaline is also known as the fight or flight hormone. It prepares the body to run away or fight.
 * Insulin- Insulin and glucose are like a door and key. There is a lock on each cell and the glucose cannot get in unless the insulin (the key) lets it in.
 * Thyroxine- it controls metabolism levels in the body and helps with growth and development.
 * [|Hormones] are a key to development in the body.

**__Diseases, Disorders and Problems-__**

 * There are two diseases that can start in the pancreas. Insulin plays a big factor in your body. If you have an undersupply of insulin you may feel thirsty all of the time, you may looses weight and get infections. If you go to the doctor they will tell you that you have sugar in your bloodstream that is not getting absorbed but it can be treated successfully.
 * Diabetes is also a serious problem with the endocrine system. There is Type one diabetes and Type two diabetes. Type one diabetes is when the insulin in your body is not working with the glucose and you would need to take shots to inject more insulin.
 * Growth and development are other problems that could occur with the endocrine system. The growth hormone is controlled by the pituitary gland, and when the gland releases too much of growth hormone or even too little can cause a growth problem. When the hormone just keeps telling the cells to grow or cutting of the growth too early can also cause a malfunction. This is why short people might take an extra dose of growth hormone.
 * Osteoporosis is another issue that could occur with the endocrine system. Osteoporosis is when the bones become frail and break easier. This could be an effect of low production levels of testosterone or estrogen.
 * The diseases that could happen are serious. Having a problem with the Endocrine System could be a disastrous issue but if treated carefully and correctly you will be fin and healthy. [|More Diseases]

__**Endocrine Fun Facts**__ -
 * The endocrine system works with the nervous system to send chemical messages throughout the body.
 * The two parts of the pituitary gland are the anterior(front) and posterior(back).
 * The thyroid is found right under the pharynx.
 * The word adrenalin is from Latin but some people call it epinephrine, which comes from the Greek language.
 * The thyroid requires iodine to make thyroxine.
 * The human body produces and contains 30 different hormones!

** __Vocabulary-__ **
 * Homeostasis- A balanced condition inside the body (also known as dynamic equilibrium) the just right point of temperature and all other things important to the body such as hormone levels.
 * Hormone's- Hormone's are substance's that flow through the body and regulate growth, development, the other systems in the body and mood. There are over 30 different hormones in the body.
 * Osteoporosis- This is when bones become brittle or frail and will break much quicker than normal, healthy bones.
 * Acromegaly- In adults this can cause a growth spurt of the hands, feet and face.
 * Stable- Not easily changed or effected, stays the same for most of the time.
 * Nervous System- Controls all other systems and helps maintain homeostasis.
 * Secrete- To release a substance formed in and given off of by a gland.
 * Stimulate- to make active or to become more active.

** ﻿ ** **﻿The Endocrine System is a very amazing system that my group members and I hope you learned a lot about. We hope you can walk away from this Wiki and be able to tell what you learned about my favorite system, the Endocrine System!!!**
