Answer
Muscular and skeletal systems
Explanation
To answer this question, it's important to understand the primary functions of the systems mentioned and how they relate to the movement of the human body.1. Muscular and Skeletal Systems: The muscular system consists of muscles that contract and move parts of the body. The skeletal system provides a framework that supports the body and works with the muscular system to facilitate movement. Muscles are attached to bones, and when they contract, they pull on the bones, causing movement.2. Circulatory and Endocrine Systems: The circulatory system is responsible for transporting blood, nutrients, gases, and wastes throughout the body. The endocrine system consists of glands that release hormones, which regulate processes such as growth, metabolism, and reproduction. While these systems are essential for overall body function, they are not directly responsible for movement.3. Excretory and Respiratory Systems: The excretory system eliminates waste products from the body, and the respiratory system is responsible for gas exchange (taking in oxygen and releasing carbon dioxide). These systems are crucial for maintaining homeostasis but do not directly cause body movement.4. Digestive and Nervous Systems: The digestive system breaks down food into nutrients, which are absorbed into the body. The nervous system controls and coordinates body activities, including movement. While the nervous system plays a key role in signaling muscles to contract, the digestive system is not directly involved in movement.Based on this analysis, the muscular and skeletal systems are the pair most directly required to make the human body move. Muscles contract to create movement, and bones provide the structure necessary for this movement.
