Answer:
<em>B. Allows blood to flow between the two ventricles </em>
<em>C. Allows blood to flow from the atria to the ventricle</em>
<em>D. Prevents blood from flowing into the atria when the ventricle pumps </em>
Explanation:
I reviewed this question using the "Roles of Your Four Heart Valves" and believe that out of the four, those two would be your best decision. Now, it says that it prevents blood from flowing BACK into the atria when blood pumps out of the ventricle, so for the second answer I had chosen it may be right or wrong since the answer didn't specify, but it should come up as correct.
answers that are <u>not correct: </u>
<em>A. Allows blood to flow between the two atria</em>
- I say this is wrong because the atria are connected and pump blood to the ventricles, and should pump between themselves. Now, whether that is what the answer is meaning or not, I would play it safe and not pick this one.
<em>Best Wishes!</em>
