What does antrum mean?
Antrum: A general term for a nearly closed cavity or chamber.

The paranasal sinuses can be referred to as the frontal antrum, ethmoid antrum, and maxillary antrum..
What does the antrum of the stomach secrete?
The pyloric antrum which secretes no hydrochloric acid functions as an endocrine organ. Its hormone, gastrin, mediates the gastric phase of gastric secre- tion. The release of gastrin is stimulated by contact of various food substances with the antral mucosa.
What are the two valves found in the stomach?
Two smooth muscle valves, or sphincters, keep the contents of the stomach contained: the cardiac or esophageal sphincter and the pyloric sphincter.
What are the four main 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 determines if a substance can or Cannot be absorbed in the stomach?
The most important factor that determines absorption within the stomach is pH. Weak organic acids, which exist in a diffusible, nonionized and lipid-soluble form are readily absorbed in the high acidity of the stomach (pH 1-3). In contrast, weak bases will be highly ionized and therefore poorly absorbed.
What are the main divisions of the stomach?
The main divisions of the stomach are the following:Cardia. The cardia is the portion of the stomach surrounding the cardioesophageal junction, or cardiac orifice (the opening of the esophagus into the stomach). … Fundus. The fundus is the enlarged portion to the left and above the cardiac orifice.Body. … Pyloric antrum.
What are the four parts of the stomach?
The human stomach is subdivided into four regions: the fundus, an expanded area curving up above the cardiac opening (the opening from the stomach into the esophagus); the body, or intermediate region, the central and largest portion; the antrum, the lowermost, somewhat funnel-shaped portion of the stomach; and the …
How long does it take for stomach lining to heal?
Acute gastritis lasts for about 2-10 days. If chronic gastritis is not treated, it may last from weeks to years.
Can you live without a stomach?
It may be surprising to learn a person can live without a stomach. But the body is able to bypass the stomach’s main function of storing and breaking down food to gradually pass to the intestines. Absent a stomach, food consumed in small quantities can move directly from the esophagus to the small intestine.
What causes inflammation in the gastric antrum?
Gastritis is inflammation of the gastric mucosa caused by any of several conditions, including infection (Helicobacter pylori), drugs (nonsteroidal anti-inflammatory drugs, alcohol), stress, and autoimmune phenomena (atrophic gastritis).
What is the function of the antrum of the stomach?
The antrum is the lower part of the stomach. The antrum holds the broken-down food until it is ready to be released into the small intestine. It is sometimes called the pyloric antrum. The pylorus is the part of the stomach that connects to the small intestine.
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.
Why would nutrients not be absorbed in the stomach?
Malabsorption is a disorder that occurs when people are unable to absorb nutrients from their diets, such as carbohydrates, fats, minerals, proteins, or vitamins. Some commonly known disorders related to malabsorption are lactose intolerance and celiac disease.
What substances are absorbed from the stomach?
The stomach absorbs very few substances, although small amounts of certain lipid-soluble compounds can be taken up, including aspirin, other non-steroidal anti-infammatory drugs, and ethanol.
Where is the antrum in the body?
structure in human digestive system The antrum, the lowermost part of the stomach, is somewhat funnel-shaped, with its wide end joining the lower part of the body and its narrow end connecting with the pyloric canal, which empties into the duodenum (the upper division of the small intestine).

Which is the fastest to be absorbed from stomach?
In this steady-state study, water absorption was fastest from the first 25 cm of intestine perfused (duodenum), followed by the adjacent 25 cm of the proximal jejunum, with the slowest water uptake from the next 25-cm segment of the perfused jejunum.
