Many microbial pathogens enter the gut o | Class 12 Biology Chapter Human Health and Disease, Human Health and Disease NCERT Solutions

Question:

Many microbial pathogens enter the gut of humans along with food. What are the preventive barriers to protect the body from such pathogens? What type of immunity do you observe in this case?

Answer:

Many microbial pathogens enter the gut of humans along with food. The preventive barriers to protect the body from such pathogens are as follows:

The coating of mucous of the epithelium lining of the gut, helps in trapping microbes that enters into the body.
Saliva in the mouth and hydrochloric acid in gastric juice is secreted by the stomach that prevents the microbial growth.

This type of immunity is innate immunity which is non- specific. It is present from birth and is inherited from parents which remains throughout the life. Many barriers are provided to the entry of foreign agents into our body. These are: physical barriers, physiological barriers, cellular barriers and cytokine barriers.
