The film explores the muscular system of the human body, detailing the roles and functions of the three types of muscles: skeletal, smooth, and cardiac. Skeletal muscles, which are voluntary and work in pairs, enable movement by contracting and pulling on bones. Smooth muscles operate involuntarily, facilitating processes like digestion and blood circulation. Cardiac muscle, found only in the heart, contracts rhythmically to pump blood. The film also explains how muscles generate energy through chemical reactions, emphasizing the importance of oxygen and the buildup of lactic acid during exertion.
