Which body system contains the heart and blood vessels for blood transport throughout the body?

The correct choice identifies the cardiovascular system as the body system that contains the heart and blood vessels responsible for transporting blood throughout the body. The heart serves as the central pump that circulates blood, which carries oxygen and nutrients to tissues while removing waste products. Blood vessels, including arteries, veins, and capillaries, form a comprehensive network facilitating this transport.

In this system, the interaction between the heart and blood vessels ensures efficient circulation, maintaining homeostasis and supporting overall bodily functions. The design and operation of the cardiovascular system are crucial for delivering essential substances to cells and tissues and are foundational to life itself. Other systems listed do not include the heart and blood vessels and have distinct roles unrelated to direct blood transport.
