The Endocrine
System

By Anastasia Anastassiou
You might be wondering, what is the
Endocrine System?

Although we rarely think about it, the
Endocrine System
influences almost every cell, organ, and function of our body which consists a number of endocrine glands throughout your body. The Endocrine System is in charge of body processes that happen slowly such growth and development, regulating mood, growth of cells and tissues, levels of glucose in blood, water levels in body, metabolism, heat production, sexual maturity and reproduction processes. The foundations of the endocrine system are the hormones and glands. As the body's chemical messengers, hormones transfer information and instructions from one set of cells to another.
Thanks For Watching my Prezi on the Endocrine System!
A
gland
is a group of cells that produces and secrets chemicals. A gland selects and removes materials from the blood, processes them, and secrets the finished chemical product for use somewhere in the body. Here are the glands that are part of the Endocrine System and the main hormones secreted by each gland.
Hypothalamus gland:
A Collection of specialized cells that are located in the lower central part of the brain. It is also the main link between the endocrine and nervous system. It produces chemicals that either stimulate or suppress hormone secretions from the pituitary
Pituitary Gland:
Located at the base of the brain just beneath the hypothalamus and is considered the most important part of the endocrine system. Its is also known as the
'master gland'
because it makes hormones that control several other endocrine glands. This gland produces growth hormones, hormones that affect sex organs and hormones that act on kidney cells.
Thyroid Gland:
Located at the front part of the lower neck, shaped like a bow or butterfly. This gland produces hormones that influence mental and physical growth.
Parathyroid Gland:
Attached to the Thyroid are 4 tiny glands that function together called the parathyroids.

This gland produces hormones that raise calcium levels.
Adrenal Glands:
Located beneath the pancreas and consists of two different parts.

This gland produces adrenalin, raises blood pressure, heartbeat and breathing rate in readiness for activity.
Reproductive Glands:
The Ovaries in females are located in her pelvis. They produce hormones that control the uterus, growth of body hair and fat cells, and growth of breasts. They produce the hormone progesterone oestrogens. Testes on a male are located in the scrotum and produce hormones that control growth of facial hair and body hair, and muscular growth. The hormones are called testosterone.

Central Nervous System
Peripheral System
The brain is the main organ
Messages are sent through neurons
To much or to little of any hormone can be harmful to your body. For example, if the pituitary gland produces to much growth hormone, a teen may grow excessively tall. If it produces to little, a teen may be unusually short. Doctors can often treat problems with the endocrine system by controlling the production of hormones or replacing certain hormones with medication.
Pancreas Gland:
The pancreas produces insulin, which lowers the level of glucose in the blood, and glucagon, which raises the level of glucose in the blood.
So far We have talked about the process of how insulin works. The video below shows the process of how insulin and glucose works but it also illustrates the problems that can occur when there is an unbalanced amount of hormones

C
ontrols muscle movement, sense, heartbeat, breathing, digestion, memory and speech
Controls, levels of glucose in blood, water levels, glucose breakdown in cells, heat production, sexual maturity, sperm and egg production and growth of cells and tissues.
Both systems enable cells to communicate with others by using chemical messengers
Insulin is one of the main hormones created in the body and is quite important as Insulin allows glucose to get into cells to provide them with energy. Insulin is the key that unlocks cells for glucose to enter and deliver energy. When insulin arrives at the cell it connects with a target cell and signals the cell to activate glucose transporters. These transporters pull the glucose through the cell walls and as it does so it delivers energy.
