Digestive System. The nemertini show a very welldeveloped digestive system. A mouth opening that is ventral to the rhynchocoel leads into the foregut, followed by the intestine. The intestine is present in the form of diverticular pouches and ends in a rectum that opens via an anus.Characteristics of Nemertea: . 1)Bilaterally symmetrical and dorsoventrally flattened. 2)Body has more than two layers of cells with tissues and organs. 3)Body has a through gut with a mouth and anus. 4)Body has no body cavity. 5)Has a blood system with blood vessels. 6)Has a well developed nervous system and a brain. nemertean digestive system

The circulatory system of nemerteans is closed, as is the digestive system, which includes separate mouth and anus (unlike flatworms, which have a single opening). The nervous system includes a brain and several nerve cords; respiration is entirely by diffusion. [4

Human digestive system: Human digestive system, the system used in the human body for the process of digestion. The human digestive system consists primarily of the digestive tract, or the series of structures and organs through which food and liquids pass during their processing into forms absorbable into the Nemertea (The Ribbon Worms) (JB) Nemerteans are capable of multiple transverse fission. You can cut them up and all the parts with form new nemerteans. Slices that are too small may form cysts around themselves to protect themselves until they are more developed. nemertean digestive system The digestive system is made up of the gastrointestinal tractalso called the GI tract or digestive tractand the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.

The liver has multiple functions, but two of its main functions within the digestive system are to make and secrete an important substance called bile and to process the blood coming from the nemertean digestive system Digestive system and body cavities flatworms have a incomplete system like a gastrovascular cavity with a single opening where excretion is completed using flame cells and they lack a coelom (acoelomate); roundworms are more complex with a complete digestive system with two opening's. Nemertea. The foregut, stomach and intestine run a little below the midline of the body, the anus is at the tip of the tail, and the mouth is under the front. A little above the gut is the rhynchocoel, a cavity which mostly runs above the midline and ends a little short of the rear of the body. How can the answer be improved? Class Cestoda and Phylum Nemertea. STUDY. PLAY. Digestive system of cestoda. greatly reduced or absent. Describe how a tapeworm feeds. It doesn't have a mouth, so it's synctial tegument skin is modified to absorb nutrients. example of Nemertean that specializes on eggs of crabs; and can wipe out an entire year's spawn (Dungeness crab).
