Which chamber of the heart is the largest chamber and responsible for pumping blood to all of the vital organs of the body?
  1. Left atrium
  2. Right atrium
  3. Left ventricle
  4. Right ventricle
Explanation
Answer - C - The largest chamber of the heart is the left ventricle. The left ventricle is primarily responsible for systemic circulation, which is circulation of blood from the heart to all parts of the body except the lungs. Because the blood in systemic circulation must reach distant parts of the body, the left ventricle is a very large chamber of the heart with powerful muscular contractions to accomplish its role.
