Heart pumping and blood flow through the heart
How blood flows- Superior Vena Cava collects
blood from upper body- Inferior Vena Cava collects
blood from lower body- Blood enters right atrium, the
moves to right ventricle- Goes through the Pulmonary
valve then through the Pulmonary Artery into the lungs to oxygenize the blood
- Blood returns through the pulmonary vein into the left atrium
- Blood moves into the left ventricle
- Blood moves into the Aortic valve and then through the Aorta
How the Heart beats
Diastole and Systole
The atria and ventricles relax (Diastole)
Right and left atria fill with blood (Diastole)
Blood then moves into the ventricles (Systole)
Ventricles contract pushing blood out of heart (Systole)
Lubb Dubb sound
Lubb sound is made by the Tricuspid Valve and the Mitral Valve closing
Dubb sound is made by the Pulmonary Valve and the Aortic Valve closing
