Question

Quizplus · Accepted Answer

Circulatory systems allow for the efficient transport of gases, nutrients, and waste products across large distances, overcoming the slow rate at which these substances can diffuse across cells. This is a significant advantage, as it allows for more rapid delivery of necessary materials and removal of waste products from cells throughout the body. The other options may relate to other advantages of circulatory systems, but they are not as directly related to the primary benefit of circulating systems as described in the question stem.
