PHYL 142 | Digestive | Peristalsis, Segmentation, & Mass Movement
Anatomy & Physiology with Dr. J・2 minutes read
The small intestines use segmentation to mix food with digestive enzymes, while the large intestines compress chyme into solid feces and reabsorb water to prevent diarrhea. A specialized assay tracks intestinal motility using guinea pig intestines to study the effects of drugs on intestinal activity.
Insights
- Small intestines use segmentation to mix food with enzymes from other organs, while large intestines reabsorb water to prevent diarrhea and store beneficial bacteria for digestion and vitamin production.
- A specialized assay developed by a medical professor tracks intestinal motility using guinea pig intestines, focusing on fecal pellet movement to evaluate drug impacts on intestinal activity.
