what is the digestive system of earthworm?
6649
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.

Benefits of earthworms By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil.

Invertebrate animals commonly called "worms" include annelids (earthworms and marine polychaete or bristle worms), nematodes (roundworms), platyhelminthes (flatworms), marine nemertean worms ("bootlace worms"), marine Chaetognatha (arrow worms), priapulid worms, and insect larvae such as grubs and maggots.

Digestive system: The system of organs responsible for getting food into and out of the body and for making use of food to keep the body healthy. The digestive system includes the salivary glands, mouth, esophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum.

Most flatworms, such as the planarian shown in Figure 1, have a gastrovascular cavity rather than a complete digestive system. In such animals, the “mouth” is also used to expel waste materials from the digestive system. Some species also have an anal opening. The gut may be a simple sac or highly branched.

The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body. The digestive organs also move waste material out of the body. The enzymes in saliva help break down foods, and the lubrication function of saliva makes it easier for food to be swallowed.

Segmented worms also tend to have organ systems that are more developed than the roundworms' or flatworms'. Earthworms, for example, have a complete digestive tract with two openings, as well as an esophagus and intestines. The circulatory system consists of paired hearts and blood vessels.

Annelids have a well-developed, closed circulatory system (one in which blood is limited to vessels) that is segmentally arranged. They also have a complete, one-way digestive tract with a mouth and anus. The digestive tract is not segmented.

Like flatworms, annelids have a mesoderm with muscle, a central nervous system, and an excretory system. ... In addition to a more specialized complete digestive system, annelid worms have also evolved body features not found in flatworms or nematodes.

Unlike the flatworms in which food and waste enter and exit from the same opening, nematodes have a complete digestive system. An animal with a complete digestive system has a mouth at one end, a long tube with specialized parts in the middle, and an anus at the other end.

The digestive system is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine (or colon), rectum, and anus. There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.

differences between earthworms and humans Earthworms have no skeleton while Humans have an endoskeleton. Earthworms have 5 aortic arches while Humans have one heart. Earthworms get oxygen through their skin while Humans breathe in and out for oxygen. Humans do not have a crop or a gizzard.

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.

As a phylum, there remain many common features that all arthropods share in their digestive systems. Their digestive system includes a foregut (pharynx and esophagus to the stomach), midgut (stomach), and hindgut (colon, anus), similar in some ways to the human digestive tract.

The digestive system is the system of the body that allows us to digest our food and absorb its nutrients. It includes organs such as the stomach and intestines. The circulatory system includes the heart and blood vessels and allows blood to be pumped all throughout the body.
