Your heart is a muscular organ, just right size to fit inside your fist. It is situated right behind your breastbone, towards the left side. Your heart is responsible for running the cardiovascular system of your body, which basically comprises of pumping blood that flows in your body through a network of veins and arteries.
Four chambers of the heart
The veins supply your right atrium with blood, and the right atrium sends it to the right ventricle, which then pumps it into your lungs. In the lungs, blood gets oxygenated, and the lungs then send it back to the left atrium through the veins, which then again pumps it into the left ventricle, and again towards the lungs to continue the cycle all over.
Your left ventricle is the strongest chamber of the heart, and it is responsible for pumping oxygenated blood to all your body organs. It is the fast contractions of the left ventricle that raise and lower our blood pressure levels.
