Muscles are vital for movement and essential bodily functions. Skeletal muscles enable voluntary movement by contracting and relaxing, allowing us to walk, grasp objects, and perform various activities.
Smooth muscles, found in organs like the digestive tract and blood vessels, help with involuntary functions such as digestion and circulation.
Cardiac muscle forms the heart and contracts rhythmically to pump blood. Muscles generate heat, contribute to posture, and protect internal organs. They store and release glucose, aiding in energy balance.
Overall, muscles are integral to mobility, metabolism, circulation, and bodily processes that sustain life and allow us to interact with the world.
