Cardiac muscle in biology

The heart works through a repeated cycle of contraction and relaxation to pump blood. This cycle has two main phases: --- 1. Systole (Contraction Phase) The atria contract first, pushing blood into the ventricles. The ventricles contract next, pumping: Oxygenated blood from the left ventricle → body Deoxygenated blood from the right ventricle → lungs Valves (mitral, tricuspid, aortic, pulmonary) close and open in sequence to ensure blood flows in one direction. --- 2. Diastole (Relaxation Phase)
