10. Why is a countercurrent exchange system a good one to use for exchanging material between an organism's blood and the external environment? A) Because this type of system has the 2 materials flowing in the same direction so that there is always a concentration gradient B) Because this type of system is the only way to obtain sufficient oxygen when using air as a respiratory medium C) Because this type of system is less efficient because it can move a large amount of material with very little energy. D) None of the above E) Because this type of system has the two materials flowing in opposite directions so that there is always a concentration gradient.
