Which organ is responsible for pumping blood throughout the body?

Explanation:
The heart is the organ responsible for pumping blood throughout the body. It is a muscular organ located in the chest cavity and functions as the central component of the circulatory system. The heart's primary role is to contract and pump oxygen-rich blood from the left side of the heart to the tissues and organs, while simultaneously returning oxygen-poor blood to the right side of the heart, where it is sent to the lungs for oxygenation. This continuous cycle of pumping is vital for maintaining the body’s blood flow, delivering nutrients and oxygen, and removing waste products. In contrast, the liver primarily functions in detoxification, nutrient metabolism, and bile production, while the brain is responsible for processing information and controlling functions of the body. The lungs, on the other hand, facilitate gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled but do not pump blood. Thus, the heart is uniquely suited for the responsibility of blood circulation, making it the correct answer to the question.
