Answer 1

Answer:

hey mate your answer is...

Explanation:

The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation.

The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth. There, the food is chewed and mixed with saliva, which contains enzymes that begin breaking down the carbohydrates in the food plus some lipid digestion via lingual lipase. Chewing increases the surface area of the food and allows an appropriately sized bolus to be produced.

The food bolus is towards the top of the esophagus and arrows pointing downward show the direction of movement of the peristaltic wave. In the center image, the food bolus and the wave movement are closer to the center of the esophagus and in the right image, the bolus and the wave are close to the bottom end of the esophagus.

Peristalsis moves food through the digestive tract with alternating waves of muscle contraction and relaxation.

Food leaves the mouth when the tongue and pharyngeal muscles propel it into the esophagus. This act of swallowing, the last voluntary act until defecation, is an example of propulsion, which refers to the movement of food through the digestive tract. It includes both the voluntary process of swallowing and the involuntary process of peristalsis. Peristalsis consists of sequential, alternating waves of contraction and relaxation of alimentary wall smooth muscles, which act to propel food along

Hope this will help you

Mark me as a brainlist

Explanation:

Ingestion:Man takes in food into mouth cavity by the joint action of the lips ,toungue and teeth

Digestion:1.Mouth-the mouth or buccal cacity is the upper expanded portion of the alimentary cannal.once placed within the mouth cavity the food is first bitten off by the front teeth the incisor and then is ground into small bits by the chewing action of the cheek,teeth,the molars,this process is called mastication

Mastication is a process of mechanical digesion. it is important because it breaks food into smallar partical giving a much larger surface area for enzymes action.it also prevents discomfort during swalling

then the food mixed with saliva and soften the food.then the food passed through food pipe then food inter the stomach there the food is charged with hcl to make food digested the juice were taken from liver and gall bladder to digest the food .then all the food transported to the small intestine there the the food is clearly digested and the left overfood is transfered to large intestine then the almost digested food is absorbed.then at last food is sent to the rectum there the juice is temporarely stored.after then it expelled out through anus
