Answer:

Internally heart is divided into four parts by septums. Two upper parts are called atria, and the lower ones are called ventricles. The two atria are separated from each by inter-atriolar septum and the right and left ventricles are separated from each other by inter-ventricular septum.

The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.

The heart has four chambers:

  • The right atrium receives blood from the veins and pumps it to the right ventricle.
  • The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.
  • The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
  • The left ventricle pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure.
