Abstract:
The ruminal epithelium is a complex tissue that serves as an important protective barrier as well as a metabolically important tissue for whole-animal energy metabolism. Up to 70% of the energetic needs of mature animals are absorbed as short-chain fatty acids through the stratified squamous epithelium, and it serves as the primary producer of ketones in fed animals. Both physical and metabolic development are incomplete at birth and are triggered by short-chain fatty acids. Regulatory control of the proliferation and differentiation necessary for normal development is a useful model for the scientific investigation of nutrient-gene interactions.

Digestive Functions of the Large Intestine
As the chyme moves to the colon, it triggers two characteristic sluggish contractions - haustral churning and mass peristalsis. Haustral churning involves the rhythmic contraction and relaxation...
Mechanical and Chemical Digestion in the Small Intestine
Mechanical digestion in the small intestine involves movements such as segmentations and migrating motility complexes (MMCs), primarily controlled by the myenteric plexus. Segmentations are localized contractions occurring in areas of the intestine distended by chyme—a mixture of partially digested food. These contractions mix chyme with digestive juices, facilitating...
