Answer 2

The muscular system is an organ system, involved majorly in the movement of the body. There are nearly 700 muscles that are connected to the bones of the skeletal system, which roughly half make up the human’s body weight. Every muscle is a different organ made of blood vessels, skeletal muscle tissue, nerves, and tendons. Muscle tissues are found in the heart, blood vessels, and digestive system.
