Stomach acid is a chemical barrier against pathogens. The low pH of the acid creates an environment in which pathogens are unable to survive and will often kill them.

The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, ‘friendly’ bacteria and white blood cells called neutrophils.
The first line of defense in the stomach against damaging acid and pepsin is the A. tight junctions of epithelial cells. B. rapid rate of epithelial cell replacement.
Gastric mucosa has a particular ability to resist acid/peptic digestion. The nature of the presumed barrier to acid and pepsin has been elusive but recent work suggests that a combination of mechanisms is likely to be involved. Amongst these the mucus gel layer combined with secretion of alkali by the surface epithelium is likely to form a first line defence. The demonstration of a pH gradient.
Special Mucus Covering. Functions: By virtue of its lubricating properties , mucous protects the gastric mucosa against mechanical injury. The mucus protects the gastric mucosa from autodigestion by e.g. pepsin and from erosion by acids and other materials that are ingested.

Stomach acid is necessary for digestion because it chemically breaks down foods. The acidity also activates other digestive enzymes which contribute to chemical digestion as well. Apart from its role in digestion, the stomach acid is the first major line of defense against invading microorganisms that enter the gut with food or drink.
The stomach acid forms the first line of defence against infection. There are many bacteria and viruses that cannot tolerate such a low pH or we can say the acidity and they get denatured.
The skin, sweat glands, mucus membranes and stomach acids are all parts of the first line of defense, which all prevent pathogens from entering the body. The skin creates a barrier against pathogens using hard proteins on its surface. The sweat glands produce a body fluid that contains acids and natural antibiotics (lysozymes) which stop bacteria and fungi from growing. The mucus membranes.
What is the first line of defense in the stomach against damaging acid and pepsin? adherent layer of mucous What is the effect of the release of cholecystokinin on the liver and gall bladder?
The body’s three lines of defense against a pathogen (germ) are: 1. Anatomical and physiological barriers-Includes skin, hair, mucous membranes, saliva, tears, stomach acid, pH, temperature.
The acid is our first line of defense against pathogens, bacteria, parasites, etc. It also helps us digest our food properly. It also helps us digest our food properly. When the body is relaxed , HCL is released into the stomach and breaks down fats into fatty acids, carbohydrates into.
Low stomach acid is called hypochlorhydria while its absence is referred to as achlorhydria. These two states have been associated with carcinoid tumours in the digestive tract. Half of the population above the age of 60 suffers from hypochlorhydria.
