Which three systems of the human body function together to move and control body parts?
(1) nervous, skeletal, and muscular
(2) muscular, endocrine, and excretory
(3) digestive, excretory, and reproductive
(4) circulatory, endocrine, and respiratory
The nervous system tells your muscles to move when they need to, whether it's a conscious decision or if it's an automatic response to stimulus (ex: moving your hand off of a hot stove because it hurts). The skeletal system supports the body and joints help things like your fingers and hips move freely. The muscular system is what reinforces the support of the skeletal system and contains the nerves that receive orders from the nervous system to move. Hope this helps!
