Anus food from mouth path

The appendix is located near the junction of the small and large intestines. Undigested remains of food are passed through a one-way muscular valve into the first part of the large intestine known as the caecum — a small pouch that acts as a temporary storage site. Digestion involves the mixing of food, its movement through the digestive tract, and the chemical breakdown of the large molecules of food into smaller molecules. Through peristalsis the esophagus is able to push food from the pharynx to the stomach, even if the individual is standing on their head. Why is digestion important? Special cells help absorbed nutrients cross the intestinal lining into your bloodstream. The salivary glands in your mouth are triggered to start producing saliva, a compound that will aid in the digestion of the meal.

Food is pushed through this muscular tube and into the stomach through a series of involuntary muscle contractions called peristalses. Where Are the Mucous Membranes Located? Plus when you add the two organs you get a total of about 25 feet of intestines.
