The digestive system is partitioned into many regions, each with a certain function. The digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. Food such as soil enters the earthworm's mouth where it is swallowed by the pharynx.

The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion play key roles in the digestive process. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal.

The liver (under the ribcage in the right upper part of the abdomen), the gallbladder (hidden just below the liver), and the pancreas (beneath the stomach) are not part of the alimentary canal, but these organs are essential to digestion.

Some functions are not delivered by the skeletal system they include the digestion process and excretion etc. and the digestions process involves the metabolism, in the absorption of nutrient and the removal of waste from the body.

Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder (Figure 1). The digestive role of the liver is to produce bile and export it to the duodenum. The gallbladder primarily stores, concentrates, and releases bile.

The wall of the large intestine has the same types of tissue that are found in other parts of the digestive tract but there are some distinguishing characteristics. The mucosa has a large number of goblet cells but does not have any villi. The longitudinal muscle layer, although present, is incomplete.

A true coelom is lined on all sides by mesoderm which gives rise to muscles that surround the gut as well as underlying the body wall. This allows more efficient digestion because food can be pushed through the digestive tract by muscles.

The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.

The gallbladder is an accessory organ of the digestive system and will be removed from the abdominal cavity.

Why egestion is not a part of excretion ? Egestion is a removal of undigested food which cannot be digested further which is removed in the form of solid or sometimes semi solid and this is related with the digestive tract and then out through the anus. ... Hence, egestion is not a part of excretion.

The gastrovascular cavity is the primary organ of digestion and circulation in two major animal phyla: the Cnidaria (including jellyfish and corals) and Platyhelminthes (flatworms). ... This cavity has only one opening to the outside which, in most cnidarians, is surrounded by tentacles for capturing prey.

The vertebrate digestive system, responsible for providing nutrients for maintaining body homeostasis, consists of two components in anurans: the digestive tract and the accessory glands. The digestive tract includes the oral cavity, pharynx, esophagus, stomach, and small and large intestine, ending in the cloaca.

The digestive system consists of the parts of the body involved in chewing and digesting feed. This system also moves the digested feed through the animal's body and absorbs the products of digestion. Different species of animals are better able to digest certain types of feeds than others.

Most flatworms, such as the planarian shown in Figure 1, have a gastrovascular cavity rather than a complete digestive system. ... Digestion is extracellular, with digested materials taken in to the cells of the gut lining by phagocytosis. One group, the cestodes, lacks a digestive system.
