请教一个问题，tpo15 阅读 The leatherback turtle

xxmdskUID: 2849092

In a countercurrent exchange system, the blood vessels carrying cooled blood from the flippers run close enough to the blood vessels carrying warm blood from the body to pick up some heat from the warmer blood vessels; thus, the heat is transformed from the outgoing to the ingoing vessels before it reaches the flipper itself.

D.When a turtle places its flipper close to its body, it is able to use its countercurrent exchange system to transfer heat from the warmer blood vessels in its body to the cooler blood vessels in its flippers.

essential information题，其他的选项我能看懂，并且这题选A也没问题，但是不明白这一选项错在哪里？

看的解析但讲的很简单，没有理解。所以请教一下大家，非常感谢！

就是说原文是说血管与血管之间相近，而不是这里的body和flipper相近是吗

是的，只说了血管的相近，但是不能推测身体和鳍相近
