Question

Quizplus · Accepted Answer

Organisms with a circulating bodily fluid that is distinct from the fluid that directly surrounds the body's cells have a closed circulatory system. In a closed circulatory system, the circulating fluid, or blood, is contained within vessels and is separate from the interstitial fluid that surrounds the body's cells. This allows for more efficient delivery of oxygen and nutrients to the cells, as well as more effective removal of waste products. Open circulatory systems, on the other hand, have a body fluid that directly bathes the tissues and organs, and is not contained within vessels.
