Which term describes the complex arrangement of connected tubes that moves blood, oxygen, nutrients, carbon dioxide, and cellular waste throughout the body?

The circulatory system is the term that describes the complex arrangement of connected tubes, including the heart, blood vessels, and veins, responsible for transporting blood throughout the body. This system is crucial for delivering oxygen and nutrients to cells and tissues while also removing carbon dioxide and cellular waste. It encompasses both the cardiovascular component, which consists of the heart and blood vessels, and the lymphatic system, which is involved in fluid regulation and immune functions but does not primarily focus on blood transport.

Understanding the circulatory system's function is vital for grasping how the body maintains homeostasis and ensures cellular health through efficient transport of essential substances.
