Explanation:

The  length of a vessel  is directly proportional to its resistance: the longer the veessel, the greater the resistance and the lower the flow. As with blood volume, this makes intuitive sense, since the increased surface area of the  vessel  will impede the flow of blood.
 
        
             
        
        
        
Human forelimbs is used for a variety of functions, such as for eating.
Similarities: They are all made from the same basic anatomical structure classified as homologous structures.
They all have this structure inherited from a common ancestor.
