Study Notes
Heart Function
- The left ventricle pumps oxygenated blood from the lungs to the rest of the body.
- The right ventricle pumps oxygen-depleted blood from the body to the lungs.
Regulation of Heartbeat
- Ventricular contraction, or depolarization, is caused by electrical impulses from the sinoatrial (SA) node.
- The electrocardiogram (ECG or EKG) records the electrical signals in the heart.
Atria Function
- The atria, or upper chambers, receive blood returning to the heart and contract to push blood into the ventricles.
