Question

List each of the mechanisms of the innate or non- specific immune system. Explain why there mechanisms are considered non-specific.

Answer 1

Non-specific immune cell is an immune cell such as a macrophage, neutrophil, or dendritic cell, that responds to many antigens, not just one antigen.The cells of the innate immune system do not have specific responses and respond to each foreign invader using the same mechanism.The non-specific immune system involves defenses that are general and ongoing. Skin, parts of the lungs, and stomach are mechanical barriers. After the pathogen enters the body, non-specific cells like macrophages attack and ingest the pathogens, and natural killer T-cells attack the pathogen directly.Its action does not depend on prior exposure to a pathogen.
