The Circulatory System Presented by Madison Marzano

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

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

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