      2/ The placenta provides O2 and nutrition to the umbilical vein. (False)

      3/ the fastest pacemakers are found in the left atrial wall (F)

      4/ The left ventricular wall is thicker than the right one because it pumps more blood, further each contraction (F)

      Hi. If you really know the answers, you know why. Just state in your own words why you believe true is true and false is false. You will probably be fine with that.
      However, it would not be wise to state that you know because your friend gave you those answers, or you were able to get the T/F part from some old test but not the descriptive part.
