Give two regions of the body where the bones act as a protection for vital organs. name the bones and the organs they protect.

The skull protects the brain,  ribs form a cage that shelters the heart and lungs

Explanation:

The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax). The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs. Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.
