Which organ pumps blood throughout the body?

Explanation:
The heart is the organ that pumps blood throughout the body. It acts as a muscular pump that contracts in a rhythmic cycle to push blood into the arteries, creating the pressure needed for circulation. Blood flows through two linked circuits: the right side sends deoxygenated blood to the lungs for gas exchange, and the left side receives that oxygenated blood and distributes it to the rest of the body. Other organs have different roles—lungs exchange gases, the liver handles metabolism and detoxification, and the kidneys filter blood and regulate fluids—so they don’t drive the overall flow of blood through the body like the heart does.
