The pyloric valve, also known as the pylorus, is a small muscular structure located at the end of the small intestine that controls the flow of food from the stomach into the small intestine. It acts as a barrier between the stomach and small intestine, preventing the contents of the stomach from entering the intestine too quickly.
The pyloric valve is made up of two main components: the pyloric sphincter, which is a ring of muscle that surrounds the opening between the stomach and small intestine, and the pyloric glands, which secrete a thick, alkaline substance called mucus to lubricate and protect the lining of the stomach and small intestine.
The pyloric valve plays a crucial role in the digestive process. When food enters the stomach, it is mixed with digestive juices and broken down into smaller particles. The pyloric valve then opens and closes in a rhythmic fashion, allowing small amounts of partially digested food to pass into the small intestine for further digestion and absorption.
Problems with the pyloric valve can lead to a variety of digestive issues, including gastroparesis, a condition in which the muscles of the stomach are unable to contract properly and push food through the pyloric valve. This can cause symptoms such as nausea, vomiting, bloating, and abdominal pain. Other conditions that can affect the pyloric valve include inflammation, scarring, and tumors.
Treatment for pyloric valve problems may include medications to help control symptoms, changes to the diet, and in some cases, surgery to repair or remove the pyloric valve.
Overall, the pyloric valve is a vital component of the digestive system, helping to control the flow of food from the stomach into the small intestine. Proper functioning of the pyloric valve is essential for optimal digestion and overall health.

Depressions between the anal columns, each called an anal sinus, secrete mucus that facilitates defecation. Colonoscopy not only allows identification of precancerous polyps, the procedure also enables them to be removed before they become malignant. In the ileum, segmentations are only about eight times per minute.

The enterocytes absorb water and salts as well as vitamins produced by your intestinal bacteria. This condition, which causes irritation and inflammation of the esophagus, is most often due to excess acid, but bile may be mixed with the acid. New York: McGraw Hill. When most of the chyme has been absorbed, the small intestinal wall becomes less distended.

The symptoms include vomiting, dehydration, hunger, constipation, and stomach cramps. Retrieved November 29, 2016. It also causes increased motility in the stomach. Causes The causes of pyloric stenosis are unknown, but genetic and environmental factors might play a role. International Journal of Radiation Oncology, Biology, Physics. These glands contain Paneth cells which secrete lysozyme and enteroendocrine cells. The ileocecal valve, located at the opening between the ileum and the large intestine, controls the flow of chyme from the small intestine to the large intestine.
