The beating of the heart in a human being is heard on the left side because:
Correct answer: B. Bigger ventricle is towards the left side
- A. Both the atria are towards the left side
- B. Bigger ventricle is towards the left side
- C. Entire heart is on the left side
- D. The aorta is on the left side
Explanation
Option B: This option is the correct answer. It states that the beating of the heart is heard on the left side because the bigger ventricle is located towards the left side. The left ventricle is thicker and more muscular than the right ventricle because it pumps blood to the entire body (systemic circulation). Thus, the sounds produced by the left ventricle's contraction and the closing of heart valves are more audible on the left side of the chest.

It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
