How many pyloric caeca does a starfish have?
The pyloric stomach is attached to the cardiac stomach. The pyloric stomach produces a digestive enzyme which breaks down food. After it breakes down food it distributes the food to each arm. It is also directly connected to the duodenum
What 2 parts of the stomach of a crayfish like of a starfish?
Both crayfish and starfish have a cardiac stomach and a pyloric stomach. The cardiac stomach is responsible for receiving and grinding food, while the pyloric stomach is responsible for digesting and absorbing nutrients.
What is the function of the pyloric caeca of a fish?
Also known as digestive caeca or hepatic caeca. Pyloric caeca (outpocketing) extends from the pyloric stomach of the starfish into each of the five arms.
How does the starfish use its two stomachs?

What is a pyloric ceca?
Pyloric ceca are finger-like projections found in the intestine of some animals, such as fish, amphibians, and insects. They increase the surface area of the intestine for absorption of nutrients and can also play a role in digestion and enzyme secretion.
What is the function of pyloric region?
The pyloris controls the rate of emptying of the stomach.
What is one function of the pyloric valve?
It serves to regulate the movement of food out of the stomach and prevents bile in the small intestine from moving back into the stomach.

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.
Pyloric sphincter function?
The pyloric sphincter is a muscular valve that controls the flow of partially digested food (chyme) from the stomach to the small intestine. It regulates the release of chyme in small amounts to ensure proper digestion and absorption of nutrients. Dysfunction of the pyloric sphincter can lead to conditions like gastritis, peptic ulcers, and gastroesophageal reflux disease.
What is the function of pilorious valve?
The pyloric valve, or pyloric sphincter, is a muscular valve located at the junction between the stomach and the small intestine. Its primary function is to regulate the passage of partially digested food (chyme) from the stomach into the duodenum, the first part of the small intestine. By opening and closing, the pyloric valve ensures that the chyme is released in a controlled manner, allowing for proper digestion and absorption of nutrients while preventing backflow into the stomach.
