Answer:
skeletal system, nervous system, and digestive system
Step-by-step explanation:
our nervous system controls our every movement (walking) and skeletal because it makes up the frame work if not we would be total blobs of jello haha. anyways but then when your eating our digestive system when we swallow if goes through the whole phase of digestive system. and then it has to come out somehow so the digestive system at the end we go ahead and do our business.
hope this helps!
