Look in this 3D video how the heart muscle works in our body

The heart is a muscular organ that pump blood throughout the body. It’s located near the center of the chest,  more on the left side of the chest cavity.  The heart pumps blood through the network of arteries and veins called the cardiovascular system. Blood flows into the right side of the heart and out to the body from the left side. During its passage, it passes through all four chambers of the heart. 

The heart has four chambers :

  • Right atrium – Deoxygenated blood enters the right atrium through the inferior and superior vena cava and and pumps blood it to the right ventricle.
  • Right ventricle –  is  pumping oxygen-depleted blood to the lungs.
  • Left atrium – Oxygen-rich blood from the lungs enters the left atrium through the pulmonary vein. Left atrium pumps blood it to the left ventricle.
  • Left ventricle  – Pumps oxygen-rich blood to the rest of the body.
