Blood Flow Through the Heart

An easy way to see the way blood flows through the heart

1. Blood Flow Through the Heart

2. Blood enters the Right Atrium (RA) through two veins: Superior Vena Cava (SVC ) - Blood from the upper half of the body Inferior Vena Cava (IVC ) - Blood from the lower half of the body Superior Vena Cava Inferior Vena Cava Rt.Atrium

3. Right Atrium contracts: Pushes blood through the Tricuspid Valve into the Right Ventricle (RV) Rt.Atrium Tricuspid Valve Rt.Ventricle

4. Right Ventricle contracts: Pushes blood through the Pulmonary Valve into the Pulmonary Artery and into the lungs for oxygen Rt.Ventricle Pulmonary Valve Pulmonary Artery - to Lungs

5. Blood returns to the heart from the lungs through the Pulmonary Veins and into the Left Atrium (LA) Pulmonary Veins From Lungs Pulmonary Veins From Lungs Lt.Atrium

6. Left Atrium contracts: Pushes blood through the Mitral Valve into the Left Ventricle (LV) Lt.Atrium Mitral Valve Lt.Ventricle

7. Left Ventricle contracts: Pushes blood through the Aortic Valve into the Aorta and out to the body Lt.Ventricle Aortic Valve Aorta Out to Upper Body and Brain Aorta Out to Lower Extremities
