Heart muscle, also known as cardiac muscle, is the tissue that makes up the walls of the heart. It's a special type of muscle that contracts to pump blood throughout your body. Unlike skeletal muscles, heart muscle works automatically without you having to think about it. It's like the engine of a car, constantly running to keep everything moving. Heart muscle is incredibly strong and durable, working non-stop for your entire life. Keeping it healthy through exercise and a good diet is vital for overall well-being.
