Answer:
innate immunity : highly specialized defenses.
Explanation:
Immunity against infectious diseases are 2 types - innate immunity and acquired immunity. Innate immunity is the type of defense mechanism which is present at birth. This type of immunity does not depend upon the immunization. This type of immunity is not highly specific as acquired immunity. Innate immunity has no memory and response in first-rate towards the antigens. The phagocytic cells, dendritic cells are some cells of the innate immune system. This changes throughout the lifetime. Different species have different innate immunity. It means different species show different susceptibility to different diseases. e.g Rats are unsusceptible to Diphtheria while men, guinea pigs are highly susceptible to Diptheria.

Answer:
The immune system response against pathogens in order to protect our cells from the damage and prevent diseases.
There are different cells in the blood including macrophages, mast cells, and natural killer cells etcetra which recognises the specific pathogen-associated molecular patterns (PAMPs) on the pathogen’s surface. PAMPs can be classified as polypeptide, carbohydrate, and nucleic acid which are expressed by bacteria, parasites, and viruses. Immune system detects "self" from the "foreign" antigen and destroy the pathogen without damaging the host cell.
Hence, immune cells detect foreign pathogens through specific pathogen-associated molecular patterns (PAMPs) on the pathogen’s surface.
