Answer 1

Smooth muscle is the muscles which help the food slide down the esophagus. Couldn't have that for pulling bones now could ya?
Cardiac muscle is the heart muscles..keep pumping and pumping..striated is the muscles in your arms and legs which pull in opposing directions so you can move. Each has it's own function. The benefit is that they all work together to preform different jobs.
