Answer: The INNATE IMMUNE response is the first line of defense of the body against pathogens or potentially pathogens. It can avoid an infection.
The ADAPTIVE IMMUNE response comes into action when innate immunity does not have the tools to act or when its action has failed.
Step-by-step explanation:
INNATE IMMUNE RESPONSE:
- The response to pathogens is nonspecific, it acts rapidly between minutes to hours.
- Recognizes certain molecular patterns in infectious agents, but its number is limited. This is because it is codified in germline, it means, every cell has it.
- The epitelium and the mucus are physical barriers that helps with the innate immune response.
- The components are: The Complement, Natural Killer cells (NK), neutrophils, macrophages, monocytes and dendritic cells.
ADAPTIVE IMMUNE RESPONSE:
- It is highly specific, and as its name, it could adapted over time. It has memory.
- It recognizes a large number of pathogens, including microorganisms, and other not necessarily infectious. It is codified by gene recombination.
- The response is mediated by Immunoglobulins.
- The components are: T cells, B cells and circulating antibodies.
