Verified step by step guidance

Step 1: Begin by understanding the concept of voluntary movement. Voluntary movement refers to actions that are consciously controlled, such as walking or picking up an object. These movements require coordination between multiple organ systems.

Step 2: Recall the role of the muscular system. The muscular system is responsible for generating force and movement by contracting muscles. Skeletal muscles, in particular, are under voluntary control.

Step 3: Consider the skeletal system's role. The skeletal system provides the framework and support for the body. Bones act as levers, and joints allow movement when muscles contract and pull on them.

Step 4: Understand how the muscular and skeletal systems work together. Skeletal muscles attach to bones via tendons, and when these muscles contract, they pull on the bones, creating movement. This collaboration is essential for voluntary motion.

Step 5: Eliminate the other options by analyzing their functions. For example, the circulatory and lymphatic systems are involved in fluid transport, the nervous and endocrine systems regulate communication and hormones, and the digestive and respiratory systems handle nutrient and oxygen exchange. None of these pairs directly enable voluntary movement like the muscular and skeletal systems do.
