To which chamber of the heart is the aorta connected?

  • Left ventricle
  • Right ventricle
  • Right auricle
  • Left auricle
Correct Answer: A. Left ventricle

Detailed Explanation

The aorta is the largest artery in the human body, responsible for carrying oxygen-rich blood from the heart to the entire body. The aorta is directly connected to the left ventricle of the heart, which is the chamber responsible for pumping blood under high pressure into systemic circulation.


When the left ventricle contracts, it sends blood into the aorta through the aortic valve, ensuring that oxygenated blood reaches all parts of the body efficiently. This process is part of the systemic circulation, which provides tissues and organs with the oxygen and nutrients necessary for proper functioning.


Other heart chambers are connected to different parts of circulation:




  • Right ventricle pumps deoxygenated blood into the pulmonary artery toward the lungs for oxygenation.




  • Right auricle (atrium) receives deoxygenated blood from the body via the vena cava.




  • Left auricle (atrium) receives oxygenated blood from the lungs via the pulmonary veins.




Understanding the connection between the aorta and the left ventricle is essential in biology because it highlights how the heart functions as a pump, maintaining the circulation of oxygenated blood throughout the body. It also explains the importance of the aortic valve in preventing backflow of blood into the ventricle.


This knowledge is critical in cardiology, physiology, and everyday science, as it helps students comprehend how the heart’s structure and function support life. Any malfunction in the left ventricle or aorta, such as in heart diseases or congenital defects, can significantly affect blood circulation and overall health.
