The pylorus is the part of the stomach that connects to the small intestine. This region includes the pyloric sphincter, which is a thick ring of muscle that acts as a valve to control the emptying of stomach contents (chyme) into the duodenum (first part of the small intestine).

What is the pylorus region?
The pylorus is the furthest part of the stomach that connects to the duodenum. It is divided into two parts, the antrum, which connects to the body of the stomach, and the pyloric canal, which connects to the duodenum.
What is the function of the pyloric and cardiac sphincter?
Cardiac sphincter prevents the backflow of stomach acids and content into the esophagus, while pyloric sphincter controls the release of chyme from the stomach into the duodenum.
What is pyloric mucosa?
The mucosal (pyloric glands) in this region look different to the gastric glands in the body of the stomach. The pits are deeper, and the glands shorter and more branched. There are fewer parietal cells, and most of the cells are mucosa secreting cells, which you can tell from the pale staining appearance.
What is the function of the pyloric stomach in a starfish?
With the stomach inside, the starfish digests the mollusk in the shell. The pyloric stomach is connected by two pyloric caeca- hollow tubes that absorbs nutrients from its food.
What is the function of pyloric sphincter Class 10?
What's its function? The pyloric sphincter serves as a kind of gateway between the stomach and the small intestine. It allows the contents of the stomach to pass into the small intestine. It also prevents partially digested food and digestive juices from reentering the stomach.
What is the primary function of the pyloric valve quizlet?
The pyloric sphincter is a band of smooth muscle at the junction between the pylorus of the stomach and the duodenum of the small intestine. It plays an important role in digestion, where it acts as a valve to controls the flow of partially digested food from the stomach to the small intestine.
Is pyloric sphincter functional or anatomical?
The pylorus is surrounded by a thick circular muscular wall that is normally tonically constricted, forming a functional (if not anatomically discrete) pyloric sphincter that controls the movement of chyme.
What is the function of mucus in gastric gland?
Gastric mucus is a glycoprotein that serves two purposes: the lubrication of food masses in order to facilitate movement within the stomach and the formation of a protective layer over the lining epithelium of the stomach cavity.
What is the function of the mucous cells in the gastric pits?
The surface mucus cells secrete mucus to line the stomach and protect it from its acid environment. The mucus contains mucin and HCO3− to neutralize stomach acid.
What is pyloric channel ulcer?
Pyloric channel ulcers are associated with a clinically recognizable syndrome character- ized by nausea and vomiting, pain after meals, and weight loss. 3. Careful radiologic examination offers the best means for detection and evaluation of the lesion.
What happens to nutrients exiting the pyloric caeca?
From there, the nutrients travel down the pyloric ducts to the pyloric ceca at the end of each arm where nutrients are absorbed and stored. Waste travels from the pyloric stomach through a short intestine and is excreted through the anus located at the top of the starfish.
What is the difference between the cardiac stomach and the pyloric stomach of the Sea Star?
Stomach. A sea star has 2 stomachs, the cardiac stomach and the pyloric stomach. ... The stomach then secretes a powerful digestive enzyme to break down the prey. When the cardiac stomach comes back into the body, the food in it is transferred to the pyloric stomach.
What is the function of hydrochloric acid for the body?
Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. It also eliminates bacteria and viruses in the stomach, protecting your body from infection.
What is the function of the large intestine?
The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.
What is the anterior region of small intestine called?
Duodenum. The duodenum by definition is the first part of the small intestine. It extends from the pyloric sphincter of the stomach, wraps around the head of the pancreas in a C-shape and ends at duodenojejunal flexure.
