15 The diagram shows the investigation of blood flow in the veins of the lower arm.

W

Z


A cloth is tightly wrapped round the arm at point Z and the veins stand out clearly. One finger
presses on the vein at W.

When another finger strokes the vein, as shown in the diagram, the vein lies flat between points
W and Y.

Some possible explanations are listed.

1
The bandage at Z prevents backflow of blood.
2
The finger pressed at W prevents more blood entering the vein
3 A valve at Y prevents backflow.
4
A valve at Z prevents more blood from entering the vein.

Which explanations of the vein lying flat are correct?
A 1 and 2
B 1 and 4
C 2 and 3
D 2 and 4


16 After muscular exercise, which blood vessel carries the most carbon dioxide?
