1. The Circulatory System
Presented by Madison Marzano

2. Role and Function
Transports food, oxygen, waste, and carbon dioxide throughout the body
These materials are carried in a fluid known as blood
Blood picks up a fresh supply of oxygen in the lungs and other important substances and carries them to parts of the body where needed
An Artery carries blood away from the heart
A vein carries blood toward the heart

3. Diseases of the Circulatory system
Atherosclerosis is when fatty material builds up in the arteries
The artery gets narrower
When very narrow a blood clot will form
Artery is clogged and the blood supply is cut off
This could cause a stroke or a heart attack
People who smoke, eat fatty foods, and get little exercise suffer from this

4. Exercises
Anything that keeps the heart pumping faster than your normal heart rate
Different sports
Running
Aerobics

5. Foods
Eat grain foods
Blueberries
Salmon
Soy protein
Oatmeal
Spinach

6. Systems it relates to…
It helps the digestive system because it transports waste out of the body
It is related to the nervous system because the brain needs a supply of blood
It’s related to the respiratory system because it helps transport oxygen

7. Chambers of the heart
#1 is the right atrium, which receives oxygen – depleted blood from the body and pumps it through to the right ventricle
#2 is the right ventricle which receives the oxygen- depleted blood from the right atrium into the lungs
#3 is the left atrium which receives oxygen – rich blood from the body and pumps it into the left ventricle
#4 is the left ventricle which receives the oxygen – rich blood from the left atrium
