c) the cardiovascular system provides a framework for muscle movement
d) the cardiovascular system delivers oxygen for muscle energy

Which best describes how the muscular system impacts movement of the human body?
a) when a muscle expands, it pulls on the bone it is connected to and the bone moves
b) when a muscles contracts, it pulls on the bone it is connected to and the bone moves
c) when a muscle contracts, it pushes on the bone it is connected to and the bone moves
d) when a muscle expands, it pushed on the bone it is connected to and the bone moves
