The path of a red blood cell through the body to the heart

1. The path of a redblood cell through the body to the heart NOTE: Use space bar to move animations By Keilan Milwain-Sedlak

2. It all starts by the left ventricle of the heart contracting and getting smaller The heart Left ventricle

3. It then pushes red blood cells into the aorta so the process of the cells traveling through a series of arteries can begin Aorta

4. Once the blood cells have travel through the arteries it then reaches the capillary Blood cells Capillary

5. Body tissue Red blood cells Oxygen molecules From there oxygen molecules then break off into the body's tissue

6. Un-oxygenated blood Body tissue This way to Heart Now the un-oxygenated blood makes its way back to the heart

7. Un-oxygenated blood is here transferred to the heart Un-oxygenated blood cells

8. Un-oxygenated blood Vain The un-oxygenated blood travels through the vain and is then sent to the right atrium

9. The right atrium Red blood cells The blood cells here get passed through the right atrium and are lead to the right ventricle

10. Right ventricle Blood cells Pulmonary arteries Oxygen molecules Lungs The blood cells pass through the right ventricle and go through the pulmonary arteries. The blood cells pick up oxygen molecules on the way and deliver them to the lungs.

11. Oxygenated blood Left ventricle Blood cells Once the oxygenated blood has been passed through the left ventricle the blood cells start the process again
