What is one difference between the sternum and the femur? the femur contains yellow marrow, but the sternum does not. the femur is involved in protection, and the sternum is involved in movement. the femur makes red blood cells, and the sternum makes white blood cells. the femur contains compact bone, but the sternum does not.

The femur contains compact bone, but the sternum does not.

Explanation:

Because it is very long, the femur has the outer layer, called the compact bone, a bit thicker than the other bones to prevent it from breaking. The largest bone in the human body is the femur, which sits on the thigh and plays an important role in supporting the skeleton. The sternum is not such a long bone and does not have the outer layer called compact bone.
