Which organ pumps blood throughout the body?

Answer and explanation

Correct answer: Heart

The heart is a muscular organ that functions as the central pump of the circulatory system. Its rhythmic contractions push blood through pulmonary circulation to the lungs and systemic circulation to the rest of the body, delivering oxygen and nutrients and carrying away wastes. The kidneys filter blood, the liver processes substances, and the lungs exchange gases; therefore option A is correct.
