Bones surround vital organs to protect them.

It is true. 

One of the primary functions of the skeletal system is to provide protection for the body's vital organs.

• Rib Cage: The rib cage surrounds and protects the heart and lungs.

• Cranium (Skull): The cranium encloses and protects the brain.

• Vertebrae (Spine): The vertebrae protect the delicate spinal cord.

• Pelvis: The pelvis protects organs in the lower abdomen, such as the bladder and reproductive organs.

This protective function is essential for the survival and proper functioning of these critical organs.
