Finally explain the causes of heartburn and why the stomach does not digest itself. Anatomy and functions. Innervation is provided via the vagus nerves and the celiac plexus.

Cells in the lining of your stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process. Acid secretion is a very important non-immunological defence against invading. The stomach has four major regions.

The wider end of the funnel the pyloric antrum connects to the body of the stomach. In animals whose stomachs contain digestive glands some of. Some textbooks describe it as being the first part of the small intestine.

Fundus the rounded often gas filled portion superior to and left of the cardia. The churning action of the stomach muscles physically breaks down the food. Below the fundus is the body the main part of the stomach.

Body the large central portion inferior to the fundus. The endocrine cells secrete hormones into the bloodstream and the exocrine cells secrete gastric juice into the lumen of the stomach. It produces enzymes substances that create chemical reactions and acids digestive juices.

However gastric juice does not digest starch sugars and fats. It acts as a temporary storage organ. Partial digestion of the food takes place here.

A bolus of food enters the stomach through the lower oesophageal sphincter which rapidly closes to prevent regurgitation of gastric secretions see part 1. Structure of pharynxThe pharynx also known as the throat is a muscular funnel that extends from the posterior end of the nasal cavity to the superior end of the esophagus and larynx. The stomach located in the upper left quadrant of the abdomen is a J-shaped organ composed predominantly of involuntary smooth muscle.

With vomiting these contractions are reversed allowing stomach contents to. Ridges of muscle tissue called rugae line the stomach. These enzymes continue the process of breaking down food into a usable form.

The stomach serves as a temporary receptacle for storage and mechanical distribution of food before it is passed into the intestine. Function of the stomach. The esophagus serves to pass food and liquids from the mouth down to the stomach.

In this article we will discuss about the function of stomach. Describe the functions of the components of gastric juice. The cardia fundus body and pylorus.

The four key components of gastric digestive function are its function as a reservoir acid secretion enzyme secretion and its role in gastrointestinal motility. The stomach is a muscular organ that is found in our upper abdomen. The stomach has four main anatomical divisions.

In the absence of food the stomach deflates inward and its mucosa and submucosa fall into a large fold called a ruga. An exocrine function that helps in digestion and an endocrine function that regulates blood sugar. Has goblet cells that secrete alkaline mucus which traps rich HC03- fluid underneath.

The smooth muscle pyloric sphincter is located at this latter point of connection and controls stomach emptying. This mix of enzymes and digestive juices breaks down food so it can pass to your small intestine. Glands in the fundus that secrete gastric juice.

Stomach saclike expansion of the digestive system between the esophagus and the small intestine. The structure comprises an outer membrane an inner membrane and a gel-like material called the matrix. The narrower end is called the pyloric canal which connects to the duodenum.
