Question

Quizplus · Accepted Answer

Segmentation, also known as mixing contractions, involves back and forth contractions that break apart the food mass and mix it with digestive juices, allowing for better absorption of nutrients. Peristalsis, on the other hand, moves the food along the GI tract, but is not specifically related to segmentation. Conscious effort is not required for segmentation, and while enzymes are involved in digestion, they do not specifically play a role in segmentation.
