There are many section in the heart, starting with:
The Superior Vena Cava, where de-oxygenated blood flows in from the body. From there the blood flows into the Right Atrium, through the Tricuspid Valve and into the Right Ventricle. After the blood is in the Right Ventricle, the blood flows out of the heart through the Inferior Vena Cava and in to the lungs, where it can be oxygenated. Once oxygenated, the blood flows back into the heart through the Pulmonary Artery. From the Pulmonary Artery the blood flows into the Left Atrium, through the Mitral Valve and into the Left Ventricle. From there the blood flows through the Pulmonary Valve to the Aorta and out into the body. The process then starts over from there.
The term for the 4 sections of the heart muscle is the cardiac muscle.
In your heart, the top two hollow sections are called atrium and the lower two are ventricles.
veins and arteries

This controlled destruction of small sections of heart muscle actually kills the nerve cells causing the irregular heartbeat, stopping the nerve signals that are passing through this section of the heart.
No, a sagittal cut would not be done to achieve anterior and posterior sections of the heart. A transverse cut would be more appropriate to separate the heart into anterior and posterior sections. A sagittal cut divides a structure into left and right portions.
precisly in the middle, the heart looks like three black sections from the outside. therefore three chambered
