Expert Solution
Step 1

Muscle is utilized to support joints and keep them protected from collapsing under stress. Smooth muscles maintain bladder continence and move food through the colon. Muscles also contribute to heat generation by shivering. In higher animals, movement is made possible by the combination of bones, muscles, and cartilage.
