Video Summary
Humans' muscular system consists of hundreds of muscles that carry out many different functions. It is made up of skeletal muscles, which are voluntary muscles that we can control, and smooth muscles, which are involuntary muscles that we cannot control. Skeletal muscles are attached to bones by tendons, and when they contract, they pull on the bones and move the body. Smooth muscles line the walls of blood vessels and organs such as the stomach and intestines, and they contract to move substances through these vessels or organs.
