Question

It does this by burrowing into the mucosal lining of the stomach and degrading it to form a hole. By doing so, what type of innate defense is it overcoming?

Answer 1

Answer:

Physical barrier

Explanation:

Innate immunity is our first line of defense against invading organisms . inmates immunity include physical barriers, antimicrobial substances, normal flora etc.

The skin and mucosa of stomach and of other organs serve as first line of defense and the function of defense is both mechanical and chemical. The mechanical function involves physical barrier that prevent entry or translocation of organisms. The chemical function include substances that inhibit growth or destroy microbes e.g. gastric acid in the stomach.

Answer 2

Answer:

Note that , the question is incomplete. The completed one is..

Heliobacter pylori is a species of bacteria that causes stomach ulcers. It does this by burrowing into the mucosal lining of the stomach and degrading it to form a hole. By doing so, what type of innate defense is it overcoming?

Species resistance

Chemical barriers

Mechanical barriers

Inflammation

Answer is Mechanical barriers

Explanation:

The mechanical barriers can be described as devices or substances that prevent or block the organisms that can cause infections, pathogens, from entering the body. Examples include, cervical cap, mucous membranes and condoms.

It should be understood that both male and female condoms are also regarded as mechanical barriers because they are devices preventing the sperm which may contains infections from entering the body.

Also, mucous membrane secrets mucus which is capable of trapping pathogens. And this mucous membrane is found in tracts, like urinary, reproductive and respiratory tracts.

In this case, the Heliobacter pylori is overcoming the mechanical barrier , specifically the mucus that is found in the stomach which is being produced by the mucous membrane.
