Question

match the body function with the two organ systems. internal organs are protected & movement is allowed.
skeletal
muscular
circulatory
nervous

Explanation:

Step1: Analyze the function

The function given is "internal organs are protected & movement is allowed". We need to find which two body systems (Skeletal, Muscular, Nervous, Circulatory) match this function.

Step2: Recall system functions

• Skeletal system: Provides structure, protects internal organs (like ribcage protecting heart/lungs), and works with muscles for movement.
• Muscular system: Works with skeletal system to enable movement (muscles contract to move bones).
• Nervous system: Controls and coordinates body functions, not directly for protection or movement in this context.
• Circulatory system: Transports blood, nutrients, etc., not for protection or movement as described.

So the two systems are Skeletal and Muscular.

Answer:

Skeletal, Muscular
