PRESENTATION OUTLINE
What is the circulatory system?
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.

Meanings
Arteries
Arteries are blood vessels that carry oxygen rich blood AWAY from the heart.
Capillaries
Capillaries are tiny blood vessels as thin or thinner than the hairs on your head. Capillaries connect arteries to veins. Food substances(nutrients), oxygen and wastes pass in and out of your blood through the capillary walls.
Veins
Veins carry blood back toward your heart.

How does the circulatory system help move your blood?
The blood is an amazing substance that is constantly flowing through our bodies.
Your blood is pumped by your heart.
Your blood travels through thousands of miles of blood vessels right within your own body.
Your blood carries nutrients, water, oxygen and waste products to and from your body cells.
A young person has about a gallon of blood. An adult has about 5 quarts.
Your blood is not just a red liquid but rather is made up of liquids, solids and small amounts of oxygen and carbon dioxide. By: Fatima!!!
How does the circulatory system help your body?
It helps deliver oxygen and nutrients that are in the blood to all the other organs in the body. Blood also collects waste products for the body to remove. Adult humans have about five liters of blood in their body.

Why is the circulatory system so important?
The importance of the circulatory system to human beings is that is keeps them alive through provision of oxygen and energy in the tissues and organs of the body. It also removes the waste material in the body and when it fails, the person dies. The system can also be referred to as the cardiovascular system.

How does the circulatory system circulate the food we eat?
When you eat food it goes in your arteries and blood cells which produce more blood and circulate it through out the body. The way this system works is your food goes in your arteries that are in your heart and the arteries pump out the blood with nutrients of the food in to the blood veins which carry the blood cells and the fresh blood from the arteries to different parts of your body.

Why do we need the circulatory system
The reason we need the circulatory system is because it is the reason you live. If there will be no circulation of blood through your body you will die and if your heart fails your circulatory system will fail too. and that is the biggest reason you need the circulatory system in your body.
