The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.

What is the significance of numerical taxonomy?</h3>
In biological systematics, numerical taxonomy is a categorization scheme that deals with the numerical grouping of taxonomic units according to their character states. Instead of employing a subjective assessment of their qualities, it seeks to construct a taxonomy using numerical procedures like cluster analysis.
The data produced can effectively be used in the design of better keys and classification systems because numerical methods are more sensitive in delimiting taxa. Numerous biological ideas that have long been accepted have been reexamined in the context of numerical taxonomy.
