WebThe heart valves allow one-way flow of blood through the heart. The right ventricle will pump blood out to the lungs so the red blood cells can become oxygenated. The P wave on the EKG graph/measurement relates to atria going through the depolarization process. Systole relates to when the ventricles are not contracting. Students also viewed WebThe heart is made up of four different blood-filled areas, and each of these areas is called a chamber. There are two chambers on each side of the heart.
