Answer 13

skeletal and muscular system work closely together but that is not the answer. the answer is the respitory and circulatory. the respitory system includes the lungs which take in oxygen and the circulatory includes the heart which is where all red blood cells get the oxygen and then it is pumped out and the red blood cells deliver the oxygen throuoght the body. they work together to bring oxygen to the body and withought them it would not be possible.
