Quizplus · Accepted Answer

Segmentation and peristalsis are the two types of muscular movements that mix and move food in the digestive tract. Segmentation involves the contraction and relaxation of circular muscles in the digestive tract, which creates a back-and-forth movement of food, while peristalsis involves the contraction and relaxation of longitudinal muscles, which propels food in one direction through the digestive tract. Therefore, choice C is the best answer.
