When the wall of the stomach Cannot protect itself from the effects of digestion the result is?
There’s a protective layer of mucus in the stomach that keeps the two warring factions apart with a special neutralizing agent. But when that mucus fails to protect the outer edge of the stomach, it begins to digest itself. You’re probably familiar with the process — it’s what creates ulcers.
What protects the stomach wall from being digested?
Your stomach protects itself from being digested by its own enzymes, or burnt by the corrosive hydrochloric acid, by secreting sticky, neutralising mucus that clings to the stomach walls. If this layer becomes damaged in any way it can result in painful and unpleasant stomach ulcers.
What effect does the stomach have on the digestive process?
The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces.
How does the stomach protect itself from being digested quizlet?
How does your stomach protect itself from being digested? The simple epithelium produces layers of bicarbonate rich in alkaline mucus that sticks to the stomach mucosa and protects the walls of the stomach.
Why is the stomach not digested by itself?
The stomach normally does not digest itself because of a mechanism which regulates gastric secretion. This checks the secretion of gastric juice before the content becomes sufficiently corrosive to damage the mucosa. Pure gastric juice can destroy the mucosa and produce a peptic ulcer.
What protects the stomach from digesting itself quizlet?
What happens when stomach is not working properly?
The most common digestive problems are heartburn, acid peptic disease (acidity), diarrhoea, constipation, abdominal pain, cramps, heaviness, bloating, nausea, irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Not to Worry! There are many ways to help your digestive system run smoothly.
What happens if your stomach is malfunctioning?
Answer: Problems with stomach emptying (gastroparesis) occur when stomach muscles don’t work correctly. Although the underlying cause can’t always be found, damage to pacemaker cells and nerves in the stomach due to diabetes or surgery can lead to stomach muscle dysfunction.
Where does the stomach deflate in the absence of food?
In the absence of food, the stomach deflates inward, and its mucosa and submucosa fall into large folds called rugae. Figure 23.4.1 – Stomach: The stomach has four major regions: the cardia, fundus, body, and pylorus.
What is the role of the stomach in chemical digestion?
As you will see in the sections that follow, the stomach plays several important roles in chemical digestion, including the continued digestion of carbohydrates until salivary amylase is inactivated by stomach acid, and the initial digestion of proteins and triglycerides.
Why does the stomach hold more food than the small intestine?
You can ingest a meal far more quickly than it can be digested and absorbed by the small intestine. Thus, the stomach holds food and parses only small amounts into the small intestine at a time.
Is the stomach the location where digestion takes place?
Popular culture tends to refer to the stomach as the location where all digestion takes place. Of course, this is not true. An important function of the stomach is to serve as a temporary holding chamber. You can ingest a meal far more quickly than it can be digested and absorbed by the small intestine.
