Question

which system is responsible for providing support, protection, and provides sites for muscle attachments?
○ integumentary
○ urinary
○ skeletal
○ respiratory

Explanation:

• The Integumentary system (skin, hair, nails) mainly protects, regulates temperature, and senses; it doesn't provide support or muscle attachment sites.
• The Urinary system filters blood, produces urine, and maintains fluid balance; it has no role in support or muscle attachment.
• The Skeletal system (bones, cartilage, ligaments) provides structural support, protects internal organs (e.g., ribcage protects heart/lungs), and bones are sites for muscle attachments (via tendons).
• The Respiratory system (lungs, airways) is for gas exchange (oxygen intake, carbon dioxide release); it doesn't support the body or attach muscles.

Answer:

C. Skeletal
