Question

(according to digestion)peristalsis occurs in which part ???

Answer 1

In much of a digestive tract such as the human gastrointestinal tract, smooth muscle tissue contracts in sequence to produce a peristaltic wave, which propels a ball of food (called a bolus while in the esophagus and upper gastrointestinal tract and chyme in the stomach) along the tract.

Answer 2

Peristalsis plays a key role in each stage of the digestive process by ensuring food moves through each stage efficiently.

Once digested in the stomach peristalsis moves foods towards the small intestines where fats, carbohydrates and proteins are converted and absorbed into the bodies cells.

Once these nutrients are absorbed, the next stage of the digestive process is carried out by the colon are large intestine. The colon is responsible for preparing whatever is left over after the nutrients have been absorbed. These leftovers are usually insoluble fibers, indigestible foods, dead cells and bacteria.

The main job of the colon is to absorb water from the chime, a term used to describe digested food after it leaves the stomach. The colon can absorb up to one litre of water and this is used to soften the stool, this helps to move it along the intestinal canal more easily.

Its important at this stage for peristalsis to push the stool along, so that its eliminated quickly.
