What is the opening between the stomach and small intestine?
The opening between the stomach and the small intestine is the pylorus, and the very powerful sphincter, which regulates the passage of chyme into the duodenum, is called the pyloric sphincter.
What branch of the large intestine is a dead end?
8. At the end of the ileum, where it widens to become the large intestine, a “dead-end” branch is visible. This is the cecum. The cecum helps the pig digest plant material.
What is the opening valve between stomach and small intestine in a pig?
This is a view of the abdomen from the pig’s left side (rostral to the top and caudal to the bottom), with the stomach cut open. With the stomach opened, the pyloric sphincter (the ring-like involuntary muscle that controls the movement of chyme from the stomach into the small intestine) is visible.
What is the last stretch of large intestine?
The sigmoid colon is part of the large intestine — the last stretch digested food travels before reaching the colon to be excreted as feces. The sigmoid colon is the last section of the large intestine that connects the descending colon to the rectum.
What is the name of the sphincter between the esophagus and stomach?
The lower esophageal sphincter (LES) is a bundle of muscles at the low end of the esophagus, where it meets the stomach. When the LES is closed, it prevents acid and stomach contents from traveling backwards from the stomach.
Do fetal pig have teeth?
Like all young mammals, fetal pigs have milk teeth (baby teeth) that are later replaced by permanent teeth.
What is the valve between the stomach and small intestine?
The pyloric sphincter is a ring of smooth muscle that connects the stomach and small intestine. It opens and closes to control the passage of partially digested food and stomach juices from the pylorus to the duodenum.
What is the difference between the atria and ventricles in a fetal pig?
Pigs like other mammals have a four-chambered heart. Each side of the heart has two chambers, the upper chambers are called atria and the lower chambers are called the ventricles.
What is the name of the tubular organ that connects the pharynx with the stomach?
esophagus, also spelled oesophagus, relatively straight muscular tube through which food passes from the pharynx to the stomach. The esophagus can contract or expand to allow for the passage of food.
Where are the two valves found in the stomach?
One valve sits between the oesophagus and the stomach, the lower oesophageal sphincter, and the other ones sits between the stomach and the small intestine, the pyloric sphincter.
