How is the heart structured?
The coronary heart has 4 chambers, on every side, one above the other. The pinnacle chambers are called the left atrium and proper atrium. The decrease chambers are the left and proper ventricles. A wall of muscle separates the left and the proper aspects of the coronary heart. The proper atrium gets unclean blood complete of carbon dioxide from the frame. When the atrium is complete, a valve opens and blood flows into the proper ventricle below. From the proper ventricle, the unclean blood is despatched to the lungs. The lungs breathe out the carbon dioxide contained withinside the blood and breathe in oxygen which the frame needs. The blood, now complete of oxygen, enters the left atrium. When the left atrium is complete, the blood flows into the left ventricle from in which it is pumped to all elements of the frame. This is referred to as the cardiac cycle.
