Which system is responsible for transporting blood through the body via vessels to the heart and lungs?

• A. Nervous system
• B. Endocrine system
• C. Circulatory system
• D. Digestive system

Answer: (C)

The circulatory system is the network that moves blood through the body via vessels, with the heart acting as the pump. Blood travels in arteries to tissues and returns through veins, while two main circuits organize this flow: the pulmonary circuit sends blood to the lungs to pick up oxygen and release carbon dioxide, and the systemic circuit delivers oxygen-rich blood to the rest of the body and brings deoxygenated blood back to the heart. This system is what physically transports blood throughout the body and to the heart and lungs. The nervous system, endocrine system, and digestive system have essential roles in control, signaling, and processing, but they do not serve as the vessels-driven transport system for blood itself.
