Mouth and oral structures. Little digestion of food actually takes place in the mouth. However, through the process of mastication, or chewing, food is prepared in the mouth for transport through the upper digestive tract into the stomach and small intestine, where the principal digestive processes take place.Chewing is the first mechanical process to which food is …

The gizzard grinds food one more time before it enters the stomach. The crop opens into a short, muscular organ, the gizzard where grinding of food takes place. Crop holds swallowed food until a toothy section of the digestive tract called the proventriculus, can pulverise it. Mesenteron also called the midgut functions mainly for digestion.

The final digestion of food takes place in the small intestine. It is also here, especially at the lower portion of the small intestine, that most of the digested food is absorbed.

The gizzard uses stones that the earthworm eats to completely grind the food. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process. The intestinal wall has blood vessels where the absorption of the digested food takes place and is transported to the rest of the body.

From proventriculus the food enters the gizzard where mechanical breakdown of food takes place by muscular contractions of gizzard wall and grinding action of small stones inside the lumen of gizzard. In gizzard little digestion of food occurs and it is made acidic by secretion of its walls which have many hydrogen ions.

Surprisingly, earthworms have quite a few digestive organs in common with humans. Digestion starts in the mouth, which takes in soil. The food is then transferred to the pharynx, which swallows the dirt into the esophagus. Instead of a stomach, earthworms have a crop which stores food and connects to the gizzard.

Our teeth help us in cutting down the food and grinding it. Incisors and canines (the front teeth) are used to cut and tear food, while the bicuspids and molars (the teeth further back) crush and grind, which in turn smashes the food into smaller bits that are easier to digest. • Tongue.

The first process is mechanical digestion. Mechanical digestion happens when physical structures degrade food. Mechanical digestion is the chewing, churning, grinding, and mixing that takes place first in the mouth and then, after the food has been swallowed, by the stomach as it moves food around to coat it in digestive acids.
