Which two body systems are primarily responsible for movement in the human body?

• A. Integumentary and lymphatic systems
• B. Muscular and skeletal systems
• C. Digestive and respiratory systems
• D. Nervous and endocrine systems

Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the concept of movement in the human body. Movement is primarily facilitated by the interaction of systems that generate force and provide structural support.
2. Step 2: Recall the role of the muscular system. Muscles contract and relax to produce movement, and they are attached to bones via tendons to exert force on the skeletal system.
3. Step 3: Consider the skeletal system. Bones provide the rigid framework and joints that allow for movement when acted upon by muscles. Together, these systems form the musculoskeletal system.
4. Step 4: Eliminate the other options by analyzing their primary functions. For example, the integumentary system protects the body, the lymphatic system supports immunity, and the digestive and respiratory systems focus on nutrient and oxygen delivery rather than movement.
5. Step 5: Conclude that the muscular and skeletal systems are the two body systems primarily responsible for movement, as they work together to produce and support motion.
