What is 14 Fascinating Muscular System Facts about?

The muscular system allows the body to move and maintain posture through three types of muscles: smooth, cardiac, and skeletal. There are over 600 muscles in the human body, with the largest being the gluteus maximus and the strongest per size being the masseter jaw muscle. Muscles are attached to bones via tendons and make up about 40% of total body weight. The heart is the hardest working muscle, pumping 2,500 gallons of blood daily.
