it is the thing that passes throug the stomach
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.
Both are ring like muscles and keep something in. They are both part of the digestive tract. A cardiac Sphincter is a tight ringlike muscle at the end of the esophagus, and before the stomach that keeps a horse from belching or vomiting. A pyloric Sphincter is basic anatomy for anyone. This is also a tight ring like muscles at the end of the stomach that keeps the stomach acids in the stomach and not spilling into the rest of the digestive tract.
No. A cow's heart is comprised of cardiac muscle and epidermis tissue that form the valves and chambers of the heart. Just like in humans, there is no bone in the heart of a cow or any other mammal for that matter.
Twelve cows can be called a flink, a dozen head or a herd of cows.
Cows were not invented.
What is the function of the cardiac sphincter?
The Cardiac sphincter prevents regurgitation of food from the stomach.
The cardiac sphincter or aka GE junction contracts at the distal end of the esophagus. So food enters into the stomach when the cardiac sphincter is relaxed.
cardiac sphincter/lower esophageal sphincter (LES)
The cardiac sphincter and the pyloric sphincter.
The cardiac sphincter is the valve between the esophagus and the stomach.
What is the function of the cardiac sphincter?
The sphincter at the top of the stomach is called the cardiac sphincter because it is located near the heart, which is known as the cardiac region. This sphincter helps regulate the passage of food from the esophagus into the stomach, preventing backflow of stomach contents into the esophagus.
The esophageal sphincter ,which allows food to enter the stomach, and stops the acidic contents from entering the esophagus.
cardiac sphincter
It is known as the lower esophageal sphincter or sometimes the cardioesophageal sphincter.
cardiac sphincter; or gastroesophageal sphincter; or lower esophageal sphincter (LES); or esophageal sphincter from http://en.wikipedia.org/wiki/Cardia
