Movement of the human body is due to the muscular system. Every muscle is a discrete organ composed of skeletal muscle tissues, tendons, blood vessels and nerves. Muscular tissues are also present inside the digestive organs, heart and blood vessels. Such organs possessing muscles assist in moving substances all through the body.
