WebWhy is an open circulatory system less efficient than a closed circulatory system? A. Metabolic wastes cannot be removed from tissues in an open circulatory system. B. There is no heart to pump the blood in an open circulatory system. C. It is more difficult to quickly deliver O2 to specific tissues when needed with an open circulatory system.
WebIn a closed circulatory system, blood is contained inside blood vessels and circulates unidirectionally from the heart around the systemic circulatory route, then returns to the heart again. As opposed to a closed system, arthropods—including insects, crustaceans, and most mollusks—have an open circulatory system.
