What are 3 functions of the stomach?
The stomach has 3 main functions:temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer.mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach.digestion of food.
What are the four functions of the stomach?
The core function of the human stomach is as an aid to diges- tion. The four key components of gastric digestive function are its function as a reservoir, acid secretion, enzyme secre- tion and its role in gastrointestinal motility.
What is the role of the stomach in the digestive system?
This is where digestive juices and enzymes break down the food that you chewed and swallowed. It prepares it to provide your body with energy. The stomach makes several digestive juices and enzymes that mix with food. Next, the stomach’s strong muscles act like a blender to turn food into a useable form.

The convex lateral surface of the stomach is called the greater curvature; the concave medial border is the lesser curvature.
Why is the stomach important?
The stomach is the main food storage tank of the body. If it were not for the stomach’s storage capacity, we would have to eat constantly instead of just a few times each day. The stomach also secretes a mixture of acid, mucus, and digestive enzymes that helps to digest and sanitize our food while it is being stored.
How long is the cardia of the stomach?
According to Ozde, this true gastric cardia normally measures less than 0.4 cm (their abstract mistakenly states 0.4 mm) and “is typically composed of pure mucous glands, or mixed mucous/oxyntic glands that are histologically indistinguishable from metaplastic mucinous columnar epithelium of the distal esophagus” (p.
