Increased venous tone will

A) relax the veins.
B) help return blood to the heart.
C) allow blood to pool in the veins.
D) stabilize blood velocity in the veins.
E) dilate the veins.

Increased venous tone refers to the increased contraction of the smooth muscle in the vein walls, which decreases the diameter of the veins. This helps to push blood back towards the heart, aiding in venous return. It does not relax, dilate the veins, or allow blood to pool in the veins, nor does it directly stabilize blood velocity.
