The digestive system of a starfish takes up most of the center and extends into the arms. The mouth opens into a short esophagus that leads into the stomach (which is divided by constriction into a larger cardiac and smaller pyloric portions.
It shows sphincter muscles.

It, is capable of great expansion and redution. Digestive System.

Starfish are carnivores and scavengers. Food can be brought into the stomach through the mouth or, in many species, the cardiac stomach can be extended out through the mouth to digest food outside the body.

1. The pyloric stomach is connected to both the anus and to the pyloric dusts and pyloric cecum. The Brusca is a cut-away view of the digestive system and associated structures. digestive system The beginning of the process- Starfish have a unique digestive system with a mouth at the center of their underside and an anus on their upper surface. The top of the starfish is up; one ray extends off to the right. Sea stars can push their stomachs outside of their body and insert it into … This leads into stom­ach.

Mouth : It is present on the oral surface. Food can be brought into the stomach through the mouth or, in many species, the cardiac stomach can be extended out through the mouth to digest food outside the body. Digestive enzymes are released, liquifying the food so the starfish can sip the liquid into its stomach. Starfish have a unique digestive system with a mouth at the center of their underside and an anus on their upper surface. 2. Starfish have a complete digestive system with a mouth at the center of their underside and an anus on their upper surface. The figure below (from Brusca and Brusca) is a cut-away view of the digestive system and associated structures. Stomach: It shows cardiac and pyloric parts. A continuous digestive tract which enables food to be continually taken in at one end and the waste products to be eliminated at the other is refered to as a through-gut. They have simple digestive systems when compared to other animals. The starfish then pushes its cardiac stomach out of its mouth into the food.

In many, the mouth is on the underside and the anus on the top surface of the animal. The top of the starfish is up, one ray extends off to the right. The digestive system. Starfish have a complete digestive system with a mouth centrally beneath and an anus on their upper surface. The mouth of the creature is in the center of the oral surface.

A small intestine runs from the secondary stomach to the anus.
Learn about the digestive system of the phylum Echinodermata - invertebrates that include starfish, sea urchins, and sand dollars. They then use their tube feet to pass the food to the stomach. The digestive system of the starfish begins at the mouth, and the food goes into the cardiac stomach which connect to the pyloric stomach. Food can be brought into the stomach through the mouth or, in many species, the cardiac stomach can be extended out through the mouth to digest food outside the body. Oesophagus: Mouth leads into short oesophagus.

Starfish have a unique digestive system with a mouth at the center of their underside and an anus on their upper surface.Partially digested food is passed to the inside of the starfish where digestion continues in the pyloric stomach. Rather, it brings the prey to the mouth located near the center of its body. The starfish does not consume prey. Echinoderms have a simple digestive system with a mouth, stomachs, intestineand anus. Starfish have a complete digestive system with a mouth at the center of their underside (the "oral" side) and an anus on their upper surface (the "aboral" side). Starfish have their mouth on the underside of the center of the disc, the digestive system consists of a large stomach that occupies much of the central disc and then extensions that project along each of the arms. The digestive system, in a functional sense, starts at the mouth, with the teeth used to capture prey or collect plant foods.Mouth shape and tooth structure vary greatly in fishes, depending on the kind of food normally eaten. 3.
