The muscular system is made up of tissues that work with the skeletal system to control movement of the body. Some musclesâlike the ones in your arms and legsâare voluntary, meaning that you decide when to move them. Other muscles, like the ones in your stomach, heart, intestines and other organs, are involuntary. This means that they are controlled automatically by the nervous system and hormonesâyou often don't even realize they're at work. The body is made up of three types of muscle tissue: skeletal, smooth and cardiac. Each of these has the ability to contract and expand, which allows the body to move and function. . 1  Skeletal muscles help the body move.
Organ systems often work together to do complicated tasks. For example, after a large meal is eaten, several organ systems work together to help the digestive system obtain more blood to perform its functions. The digestive system enlists the aid of the cardiovascular system and the nervous system (see Overview of the Nervous System).
