Smooth muscles
are also called visceral muscles because they are mostly found surrounding the
different organs of the body. These muscles serve as cushion or protections for
organs that are mostly found within the abdominal cavity. Unlike skeletal muscles, this muscles move involuntarily,
or on their own. They are composed of bundles of specialized cells capable of
contracting and relaxing to create movements, like the process of the small and
large intestines during digestion, and the function of the rectum during
excretion.
