what body system is made up of parts that move substances to all other parts of the body
The muscular system is made up of tissues that work with the skeletal system to control movement of the body. Some musclesâlike the ones in your arms and legsâare 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 hormonesâyou often don't even realize they're at work. The body is made up of three types of muscle tissue: skeletal, smooth and cardiac.
