GENERAL HISTOLOGY

Detailed explanation-1: -Increased peristalsis is called hypermotility or hyperperistalsis. It leads to diarrhea and problems with digestion when the GI tract doesn’t have enough time to break food down properly and absorb its nutrients. Decreased peristalsis is called hypomotility or hypoperistalsis.

Detailed explanation-2: -Peristaltic Waves Move Nutrients and Waste Through the Intestines. Most nutrient absorption from the foods we eat occurs in the small intestine. When chyme passes from the stomach into the small intestine, peristaltic waves shift it back and forth and mix it with digestive enzymes and fluids.

Detailed explanation-3: -When an inflammatory condition of the small bowel exists, or when irritating substances are present in the intraluminal contents, a peristaltic contraction may travel over a considerable distance of the small intestine; this is called the peristaltic rush.

Detailed explanation-4: -Peristaltic waves start as weak contractions at the beginning of the stomach and progressively become stronger as they near the distal stomach regions. The waves help to mix the stomach contents and propel food to the small intestine.
