Which of the following is not a function of the skeletal system? A.
provides a framework for the body
B.
provides protection for internal organs
C.
movement of bones
D.
production of new blood cells

C

Explanation:

The skeleton relies upon the contraction and relaxation of muscles which are attached to bone in order to move. The muscular system is made up of three types of muscle, one of which is responsible for the movement of bone. To add to the confusion, the relationship between both muscles and bones is often lumped together as the musculoskeletal system, but to be sure, they are unique in their own ways.

In summary, bones can't move on their own, and therefore movement cannot be the skeletal system's function.
