Based on "CONCEPT CHECK 42.1" Question 1, what is a key similarity between the flow of hemolymph in an open circulatory system and the flow of water through an outdoor fountain?

  • A: Both involve a continuous, enclosed circuit where fluid always remains within vessels.
  • B: In both systems, the fluid is pumped into a cavity and bathes the surrounding tissues directly.
  • C: Both rely on a strong, central pump to maintain high, constant pressure throughout the system.
  • D: The fluid in both systems is strictly separated from interstitial fluid.

Explanation

The key similarity highlighted by the question is that in both an open circulatory system and an outdoor fountain, the circulating fluid hemolymph or water leaves the confines of vessels or pipes to directly bathe or interact with the surrounding structures or environment, rather than remaining strictly enclosed within a continuous network of vessels.
