Describe the structures involved in blood flow for the starfish?
The stomach of a starfish has an extension known as a 'pyloric cecum'. This extends through each arm of the starfish, and supplies the nutrients directly to the rest of the starfish's body. As such, no blood flow or other sort of circulatory system is needed. In fact, starfish don't even have blood.
What is the function of the plyoric muscle?
The pyloric muscle is in a ring shape and is responsible for keeping the pyloric sphincter closed , until it is time to allow some of the contents of the stomach to enter the small intestine.
What is pre-pyloric?
The bottom of the stomach is the pyloric area, with the pyloric sphincter separating the stomach from the duodenum (first portion of the small intestine). The top of the stomach is the cardiac area with the cardiac sphincter. The pre-pyloric area is the area just above the phyloric sphincter where they do biopsies to test for an H-Pylori infection. The pyloric area consists of two parts the pyloric canal and the pyloric antrum.
Which animal can take his stomach out?
There is no animal that can take its stomach out. It's impossible but there are some animals that can flip their stomachs inside out. One of those animals is the starfish. Another is the great white shark..Fun Fact: Starfish have two stomachs: the cardiac stomach and the pyloric stomach. The cardiac stomach is a sack like stomach located at the center of the body and may be pushed out of the body to engulf and digest food. Some species are able to force open the shells of clams and mussels by injecting their stomachs into the shells. With the stomach inserted inside the shell, the starfish is able to digest the mollusk in place. The cardiac stomach is then brought back inside the body, and the partially digested food is moved to the pyloric stomach. Further digestion occurs in the intestine.
