Each of these are true about this system EXCEPT

• This system requires oxygen taken in by the respiratory system.

• The system works with the integumentary system to sense pain and changes in the environment.

• The system's electrical impulses work best when you are hydrated.

• This system is told what to do by the circulatory system.

Sometimes the muscular and skeletal system are called the muscoskeletal system. What is the logical reason why?

• Your bones are attached by organs of the muscular system.

• The bones make blood your muscles need.

PICK TWO

• heart

• liver

• kidney

• bones
