Healthy Skeletal and Muscular Systems: Your Skeletal System

The video tutorial explains the structure and function of the skeletal system. It begins by describing the hardness of the skull due to the bone, a tough material made of minerals. Bones are living tissues that use energy and oxygen for growth and repair. The video also covers cartilage, a soft connective tissue found in various parts of the body. The skeletal system is crucial for providing structure, enabling movement, protecting vital organs, and producing red blood cells.
