What 4 sphincters are associated with the gi tract?
The four bodily sphincters are the: 1. lower esophageal sphincter, or cardiac sphincter (esophagus to the stomach)2. Pyloric sphincter (stomach to small intestines)3. Ileocecal sphincter or valve (small intestines to large intestines)4. Anal sphincter (rectum to outside)
What is the function of the esophagus stomach valve in the digestive system?
The esophagus-stomach valve, also known as the lower esophageal sphincter, is a muscle that controls the flow of food and liquids from the esophagus into the stomach. Its main function is to prevent stomach contents from flowing back up into the esophagus, helping to prevent acid reflux and heartburn.
How is the esophagus connected to the stomach in the human digestive system?
The esophagus is connected to the stomach through a muscular valve called the lower esophageal sphincter. This valve opens to allow food to pass from the esophagus into the stomach and then closes to prevent stomach contents from flowing back up into the esophagus.

Where does a bolus of carbohydrates travel in the digestive system from mouth to anus?
Bolus goes down esophagus, through lower esophageal sphincter (aka, cardiac sphincter) and into stomach. (A sphincter is a circular muscle which squeezes shut or opens the tubular digestive tract). It then passes through pyloric sphincter into small intestine. The small intestine is made up first of the duodenum, then jejunum, then ileum. From ileum, bolus goes to ascending colon, then transverse colon, then descending colon. From there to rectum and then out through anus (anal sphincter) .
Where are the spincters in the digestive system?
1st: inferior esophageal sphincter (near esophagus passin through the diaphragm, prevents the reflux of gastric juices into the esophagus). 2nd: pyloric sphincter (at the pyloric part of stomach, controls the flow of contents from the stomach into the duodenum). 3rd: internal, external anal sphincter (lies in the anal canal and controls the discharge of wastes).
What is a sphincter in the digestive system?

What is the function of the organs in the digestive system?
the function of organs in the digestive system is to break down food

What is Guards entrances and exits of digestive system mean?
If you're referring to sphincters "guarding" entrances and exits, it means that these specific muscles close the structure to prevent backflow of body fluid. Ex: there is a sphincter between the esophagus and the stomach that "guards" the entrance to prevent the very acidic gastric juice from entering the esophagus and damaging the lining. The muscles around the eye and mouth can also be considered sphincters.
