Different parts of the human heart performs all functionalities of the heart

The Human Heart

The heart is one of the most important organs not only in the circulatory system but in all parts of the body as well. Heart is a body organ found on living organisms. For humans, human heart is larger than their fists; weigh from 250 to 350 grams and beats an average of 72 beats per minute or equivalent to 2.6 billion heartbeats in an average lifespan of 70 years. The human heart is located at the center thorax.

The main functions of the heart are to pump blood to the different parts of the body through repetitive rhythmic contraction. On average, a normal human heart pumps around 2 000 gallons of blood everyday, passing through the blood vessels to the different organs of the body. But what make these functions of the heart possible are those parts which the heart is made up of.

Parts of the Human Heart

The human heart is made up of the following parts:

  • Aorta – the largest artery not only in the heart but in the human body as well. The aorta acts as a conduit for oxygenated blood to travel from the heart to the different parts of the human body.
  • Inferior Vena Ceva – acts as the passage way for the deoxygenated blood coming from the lower parts of the body to return to the heart.
  • Left Atrium –receives the oxygenated blood from lungs, and pumps it to the left ventricle by the atrioventricular valve.
  • Left Ventricle – the largest among the four chambers of the heart. It receives oxygenated blood coming from the left atrium, then pushes blood into other parts of the body through aortic valve.
  • Pulmonary Arteries – transmit blood coming from the heart to the lungs to get oxygen.
  • Pulmonary Veins – transmit oxygenated blood from the lungs down to the heart.
  • Right Atrium – receives deoxygenated blood coming from different parts of the body.
  • Right Ventricle – receives deoxygenated blood from the right atrium then transmit it to the lungs though pulmonary valve.

These parts of the human heart are synchronized and work together in order for the human body to survive.
