Peristalsis is a series of rhythmic contractions and relaxations of the smooth muscle tissue within the digestive system. This action moves food through the tubular organs of the digestive tract. To observe peristalsis, click and drag the food to the mouth of the pig.
The skeleton not only provides shape, support, and protection, but it also works with our muscular system to enable movement. Skeletal muscles usually function in opposing pairs called antagonistic muscles. Click on the biceps of the pig to observe this action.
