Answer 2

The skeletal system provides the structural framework of the body and protects the internal organs such as the heart, lungs, and brain.

Explanation:

• The skeletal system includes all the bones and joints of the body.
• Each bone is a complex living organ composed of many cells, protein fibers and minerals.
• The skeleton serves as a scaffold by providing support and protection for the soft tissues that make up the rest of the body.
• The human skeleton is the internal structure of the human body.
• It is made up of about 270 bones at birth - after some bones have fused together, this total is reduced to about 206 bones by adulthood.
• Bone mass in the skeleton accounts for about 14% of total body weight and reaches maximum density around the age of 21.
