muscular system #healthyliving

The muscular system consists of skeletal, smooth, and cardiac muscles, enabling movement, posture, circulation, digestion, and heat production. Skeletal muscles control voluntary movements, smooth muscles manage internal organ function, and cardiac muscle pumps blood. Muscle contraction is driven by the interaction of actin and myosin filaments. Regular exercise, a balanced diet, hydration, proper rest, and stretching are essential for maintaining a healthy muscular system. Understanding how this system works helps improve overall health and physical performance.
