What are Hormones and What Do they Do?

What is a Hormone?

Hormones are secreted by the glands of internal secretion, which means that they are excreted in the body.
They are also called glands without drainage, because they do not send their products in the channels, but directly into the bloodstream.
Hormones also create some organs such as the liver and kidneys, but most of the hormones are product of the glands.

What do hormones do?

Each hormone has its own special function in the body.
In general, the task of hormones is to regulate internal body functions such as growth, nutrition esc., stockpiling of nutrients and their use, as well as the processes of reproduction. If glands produce too much or insufficient hormones, it can lead to abnormal physical appearance of the human.
Here's what some of the major glands and hormones work in our bodies.

Pituitary Gland Function

The pituitary gland is the most important of all, because it manages the work of all other glands of internal secretion. Its size is really surprising: this important gland is about as big as a pea, and nearly as much heavy. It was added to the lower surface of the brain and protected with one bone.
Although the pituitary gland is so small, it is divided into two clearly separate lobules - front and back.
Through the last lobule, which is smaller than the front, pass more than 50,000 nerve fibers.
Hormone produced in one part of the gland is tasked to encourage growth.
The pituitary gland produces two hormones that control utilization of water and fat, blood pressure and the way we regulate the heat in our body.
The pituitary gland controls and the development of sexual characteristics in both men and women. It manages and that part of the traffic of substances that has the task of turning food into different forms of energy.
The pituitary gland also affects the work of the muscles, kidneys and other organs.

Thyroid Gland Function

Thyroid gland, which is located in the neck, produces hormones that stimulate the growth and development of the body and metabolic processes in it.

Adrenal Gland Function

Above the top of both kidneys is one adrenal gland. It produces a hormone called adrenaline.
This hormone affects blood pressure response during agitation or unusual situations.
When a man is excited or frightened, it creates more of this hormone.
Other glands in the body produce hormones that influence human to behave like a boy or a girl.
As you can see, it depends from the hormones how you look and what is your health like.
