Question

Quizplus · Accepted Answer

A closed circulatory system means that blood is always enclosed within vessels and flows to and from a central pump, the heart. This allows for more efficient and directed transport of oxygen, nutrients, and waste products throughout the body. In contrast, an open circulatory system, found in some invertebrates, lacks vessels and blood flows freely throughout the body cavity, which limits the capacity and efficiency of transport.
