Use these words to fill in the blanks: biceps - bones - Cardiac muscles - cold - contract - homeostasis - Involuntary muscles - muscle - pairs - pull - shorter - Skeletal muscle - smooth muscles - triceps

A          muscle          is made of strong tissue that can contract in an orderly way. When it contracts, the cells in it become           shorter          , and when it relaxes, the cells return to their original length.                   Skeletal muscle                   is the type of muscle that attaches to         bones         and they are also called voluntary muscles. Skeletal muscles work in         pairs         because they can only        pull        and not push. An example of skeletal muscle is the          biceps          and the           triceps           in your upper arm.                       Involuntary muscles                       are muscles that you can't consciously control.                   Cardiac muscles                  , and                  smooth muscles                  are examples of involuntary muscles. The muscular system helps the body maintain               homeostasis               by shivering to warm up the body when it is very        cold        outside; also when you exercise, the cardiac muscles of your heart            contract            more often, thus pumping more blood and supplying the cells with more oxygen.
