Tear from eyes from         barriers of innate immunity :-A Physical B Cellular C Physiological D Cytokine

To answer the question, we need to identify the tear from eyes from barriers of innate immunity. The options provided are:

A) Physical B) Cellular C) Physiological D) Cytokine

Step 1: Understand the question The question is asking about the tear from eyes from barriers of innate immunity. This suggests that we are looking for a mechanism or factor that helps remove or overcome the barriers of innate immunity specifically in the eyes.

Step 2: Analyze the options A) Physical: Physical barriers refer to physical structures or mechanisms that prevent the entry of pathogens or foreign substances. In the context of the eyes, physical barriers can include the eyelids, eyelashes, and tears themselves. Tears can physically wash away pathogens or foreign substances from the eyes.

B) Cellular: Cellular barriers involve immune cells that play a role in innate immunity. These cells can detect and eliminate pathogens or foreign substances. While immune cells are present in the eyes, they may not directly contribute to tear production.

C) Physiological: Physiological barriers refer to biological processes or functions that help protect against pathogens or foreign substances. In the context of the eyes, physiological barriers can include the production of tears, which contain antimicrobial components that help fight against infections.

D) Cytokine: Cytokines are signaling molecules that regulate immune responses. While cytokines play a crucial role in immune system communication and coordination, they may not directly contribute to tear production in the eyes.

Step 3: Determine the correct answer Based on the analysis of the options, the most appropriate answer to the question is C) Physiological. Tears, which are produced physiologically, contain antimicrobial components that help remove or overcome barriers of innate immunity in the eyes.

Therefore, the correct answer is C) Physiological.
