rugae
Stomach is lined by various folds of mucous membrane and muscle tissue. These folds are termed as Rugae. This results in the characteristic appearance of stomach on the endoscopy.
The lining of a pig stomach has multiple folds called rugae. These folds churn and mix the food with the digestive juices. They also allow the stomach to stretch without rupturing the lining.
Rugae
The muscular ridges found inside the stomach are called rugae. These ridges allow the stomach to expand and contract to accommodate food and assist in the digestion process by increasing the surface area for nutrient absorption.
The ridges inside the stomach are known as rugae. They are folds in the stomach lining that allow the stomach to expand when it fills with food and liquid. Rugae also increase the surface area for gastric secretions, aiding in the digestive process by facilitating the mixing and breakdown of food.
Rugae
The inside of a frog's stomach has hard ridges. These hard ridges help mix the food with the digestive fluids when the stomach muscles churn the contents. The shape of these hard ridges is actually the shape of frog's stomach.
These ridges are fat and they allow the stomach to expand. This allows the stomach to store more food while digesting.
Ridged with rugae ridges that help to break down food particles mechanically.
The ridges are called rugae. They provide the stomach with more surface area for food. When food enters the stomach, these wrinkles expand and become stretched out. The purpose is to allow it to expand. This therefore allows expansion in volume of the pig.
The acid that is made by the stomach is called gastric acid. It is composed mainly of pepsin and other hydrochloric acids and has a pH of approximately 2; just corrosive enough to dissolve an iron nail. It is secreted from small glands lining the ridges of the stomach walls and mixes with food that has been eaten to create a liquid mixture called chyme which is then emptied into the small intestine and absorbed of its nutrients into the body.
Rugae of mucosa are folds or ridges in the lining of an organ, typically found in structures like the stomach or vagina. These structures help to increase the surface area of the organ, allowing for better absorption or expansion.
