What is your circulatory system? Heart & Blood Vessels Heart Lungs Arteries Veins

At the center of the circulatory system is your Heart which is a muscle and pumps blood throughout your body. Red= ArteriesMuscles Blue = VeinsBack to Heart Has O2 Without O2

The right side gets oxygen poor blood and pumps it to the lungs to get more oxygen. The left side gets oxygen rich blood from the lungs and sends it to the muscles and other organs. RIGHT LEFT

YOUR HEART Right Atria Right Ventricle Left Atria Left Ventricle Your heart has 4 chambers that work together to pump blood throughout your body.

LUB - DUB The sound that you hear is your Heart’s valves opening and closing between the ventricles and atria. Valves

To Lungs From Upper Body From Lower Body From Lungs To the Body To Lungs BLUE = Used Blood with NO oxygen. Red = Oxygenated blood that goes to your body.

Your Heart is a PUMP! An adult Heart Pumps 2,000 gallons of blood every day.

Blood Vessels Muscles & Organs Heart

Combined these vessels are 60,000 miles long That’s enough to wrap around the world 2 times!

Heart Disease Plaque

What causes Heart Disease? Not enough exercise. Too much fatty foods Smoking Stress

Healthy Heart Unhealthy Heart What is this yellow stuff?

WHITE BLOOD CELLS RED BLOOD CELLS

LIVE IN YOUR BODY FOR 2 WEEKS FIGHT GERMS A SINGLE DROP OF BLOOD CAN HAVE 7,000 TO 25,000 WHITE BLOOD CELLS

RED BLOOD CELLS A SINGLE DROP OF BLOOD CONTAINS MILLIONS OF RED BLOOD CELLS DELIVER OXYGEN LIVE IN YOUR BODY FOR ABOUT 120 DAYS THE CHEMICAL HEMOGLOBIN MAKES THEM RED
