Because there are a whole lot of functions which you can't (and don't want to) have conscious control over. Such as keeping your heart beating - this isn't something that you want to have to think about. You just want it to keep going - like when you are asleep or unconscious, your heart keeps beating.
Similarly, do you really want to have to consciously move your food along your intestines? Or remember to squeeze the urine down out of your kidneys into your bladder? I don't. Everything that you can do "automatically" saves your brain precious processing space. If you had to spend all your brain power on making your blood flow around your body, your lungs expand and contract, your intestines digest and your pancreas excrete insulin - it would be even harder to remember what is on your shopping list...

Additionally, muscles can be categorized as either voluntary (skeletal muscles that we can consciously control) or involuntary (smooth muscles that work without conscious effort, such as in the digestive system).
