2. What are the Heart's Chambers?

The heart has four interior chambers, two on the left and two on the right. The atria are the two small upper chambers, and the ventricles are the two larger lower chambers. The septum is the thin muscular wall separating the left chambers from the right. To remind your heart to keep pumping, the sinus node, a natural pacemaker, sends electrical signals throughout the heart.
