Verified step by step guidance

1. Begin by identifying the primary function of each organ system listed in the problem.
2. Consider the Muscular system: It is responsible for movement by contracting muscles, which pull on bones to create motion.
3. Examine the Respiratory system: Its main function is to facilitate gas exchange, providing oxygen to the body and removing carbon dioxide.
4. Look at the Endocrine system: This system regulates bodily functions through hormones, but does not directly cause movement.
5. Review the Digestive system: It breaks down food into nutrients for energy, but does not directly enable movement.
