Question

Which of the following vital organs are not protected by bones?

• A. Heart
• B. Lungs
• C. Intestines
• D. Skull

Answer 1

The correct option is C Intestines

Bone tissue performs numerous functions including:

• Support for muscles, organs, and soft tissues.
  
• Leverage and movement.
  
• Protection of vital organs, e.g. heart and lungs (protected by rib cage), brain (protected by the skull) (Note: not all vital organs are protected by bones, e.g., the intestines.)
  

So, the correct answer is option C.
