The human body has 206 bones that work together to provide support and protection for internal organs. The skeletal system is made up of two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton includes the skull, spine, ribcage, and sternum. These bones form a protective case around the heart, lungs, brain, and other vital organs. The appendicular skeleton consists of 64 bones that make up the upper and lower limbs, as well as the shoulders and hips.
