segmentation...........
To review:
Match the term segmentation with the most closely related descriptions given below:
Mesentery sheet suspending small intestine.
Propels materials through the digestive tract
Churn and fragment digestive materials
Canines
Mechanical/ chemical digestion of food
Serous membrane covering muscularis externa
Chewing
Premolars
Mesentery associated with the large intestine
Form the cheeks
Introduction:
Segmentation is the movement, which is triggered by the chemicals, hormones, and physical stimulation. In this, circular muscle layers are involved.
Explanation of Solution
Segmentation is defined as the process of contraction of circular muscles in the small intestine, wherein the activities like churning of the digestive tract content and its fragmentation and mixing occur and it creates a more uniform mixture throughout. However, no net movement is produced in a particular direction.
Therefore, it can be concluded that the term segmentation can be correctly matched with option (c) churn and fragment digestive materials.
