While studying the human body I ran into something that didn't make sense. So the human body is made up of several unique components necessary for survival such as the nervous, digestive, excretory, circulatory, skeletal, muscular and an immune systems. Each of these has several different characteristics, processes and components that allow for proper function. If all of these processes evolved one mutation at a time then how would the human survive without all of the other functions/mutations not all evolving at the same time so the organism may survive?

I suggest you take some time to learn to learn about evolution.
