The main purpose of the sphincter is to control or limit a passage way to one direction. There are two main sphincters in pigs, the cardiac sphincter that controls the passageway from the esophagus into the stomach. And the pyloric sphincter that controls the passageway into the duodenum.
the rostrum is the snout of a fetal pig
The epididymis in a fetal pig is responsible for producing sperm. It is located on one testicle in the fetal pig.
The lower trunk area on a fetal pig is called the posterior region of the pig.
The sensory papillae are located in the chest cavity of the fetal pig. These papillae are important for respiration of the pig.
The pyloric sphincter, or valve, is a strong ring of smooth muscle at the end of the pyloric canal and lets food pass from the stomach to the duodenum. It receives sympathetic innervation from celiac ganglion. http://en.wikipedia.org/wiki/Pylorus
The pyloric sphincter regulates passage of chymefrom the stomach
Controls passive from the esophagus into the stomach.
The ring like muscle that controls the flow from the stomach to the small intestine is called the pylorus or the pyloric sphincter. It is divided into two parts: the pyloric antrum which is connected to the body of the stomach and the pyloric canal which is connected to the beginning of the small intestine (the duodenum).
The pyloric sphincter regulates passage of chyme from the stomach.
pyloric sphincter valve pyloric sphincter valve
Yes, The pyloric sphincter valve regulates the exit of digested food from the stomach to the small intestine.
This is called the pyloric region. A sphincter called the pyloric sphincter is found there.
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
duodeum
The cardiac sphincter is located at the top of the stomach and controls the direction of food passing through the esophagus so that no food will re enter the esophagus. The Pyloric sphincter stops bile and digested food from entering the stomach, this valve is located at the bottom of the stomach.
