- Blood Flow Through the Heart B3 2.1
- Deoxygenated blood enters heart through the vena cava
- The dexoygenated blood enters the right atrium
- Right atrium contracts, forcing blood into the right ventricle
- Right Ventricle contracts, pumping blood through the pulmonary artery to the lungs
- Lungs oxygenate the blood
- Pulmonary vein brings oxygenated blood from the lungs back to the heart
- Blood enters left atrium
- Left atrium contracts, pumping blood into the left ventricle
- Left Ventricle contracts, pumping blood into the aorta and around the body
- Left atrium contracts, pumping blood into the left ventricle
- Blood enters left atrium
- Pulmonary vein brings oxygenated blood from the lungs back to the heart
- Lungs oxygenate the blood
- Right Ventricle contracts, pumping blood through the pulmonary artery to the lungs
- Right atrium contracts, forcing blood into the right ventricle
- The dexoygenated blood enters the right atrium
- Heart Valves ensure blood flows in the correct direction
- There are two circulatory systems, one to the lungs and one to the rest of the body
