Which body system enables movement and provides support, and includes skeletal muscles, smooth muscles, and cardiac muscles?

• A. Integumentary system
• B. Digestive system
• C. Muscular system
• D. Skeletal system

Answer: (C)

Movement and support come from muscle tissue. The muscular system includes skeletal muscles, smooth muscles, and cardiac muscles, all of which contract to produce force. Skeletal muscles attach to bones and enable voluntary movements like walking or lifting. Smooth muscles line internal organs and vessels, handling involuntary actions such as moving food through the gut and regulating blood flow. Cardiac muscle forms the heart, contracting to pump blood. Together, these muscles allow motion and help maintain posture and joint stability. The other systems don’t encompass this full set of muscle types: the integumentary system covers skin and its derivatives; the digestive system handles nutrient processing; the skeletal system provides structure with bones but does not include muscular tissue.
