Science Kids: All About The Human Skeletal and Muscular Systems

The video explores the skeletal and muscular systems, highlighting their functions and components. It explains how bones protect organs, produce blood cells, and store minerals. The skeletal system includes axial and appendicular bones, while the muscular system involves skeletal, smooth, and cardiac muscles. The interaction between these systems enables movement and supports bodily functions.

What is the primary role of the human skeletal system?

• To regulate temperature

• To produce energy

• To protect vital organs

• To digest food
