How do skeletal muscles contribute to blood flow apex?

The correct answer is that, "The skeletal-muscle pump is a series of skeletal muscles that helps the heart in the process of circulation of blood. It is especially important in increasing the venous return to the heart, but may also play a huge role in the arterial blood flow."

Through the use of the skeletal-muscle pump, it plays a vital role to help the heart in the circulation of blood in the body.

Skeletal muscles contribute to blood flow by its contraction.
Coordinated, rhythmical contractions during the exercise or some physical work enhance blood flow by the skeletal muscle pump mechanism. The muscle pump system refers to peripheral vessels, usually in the legs and arms, that have one-way valves which direct flow away from the limb and toward the heart. Those vessels compress as the muscles surrounding them contract, and they become decompressed as the muscles relax. Therefore, contraction and relaxation, make the vessels compress and decompress ( "pump").
