What is the main function of the heart?
Answer and explanation
Correct answer: Pumping blood
The governing concept is circulation. The heart is a muscular pump that contracts rhythmically: its right side sends deoxygenated blood to the lungs, and its left side sends oxygenated blood to the rest of the body. This circulation supplies oxygen and nutrients and carries wastes away. Digestion, urine formation and light detection belong to other organs, so option A is correct.
