Passive immunity: If host does not produce antibodies itself but antibodies produced in other host provides immunity, than it is known as Passive immunity. Innate immunity provides first-line defense against pathogens through physical and chemical barriers such as skin, mucous layers, and saliva. Adaptive immunity is classified into two types naturally acquired immunity and artificially acquired immunity. Innate response is produced initially for complete elimination of pathogen; a delayed response is produced in the form of adaptive immunity. Recently, the distinctions between innate and adaptive immunity have become blurred. Natural immunity is the non-specific immunity that a person has. Natural immunity describes the state of being able to resist illnesses; such a condition originates in a healthy immune system.This form of immunity is resistance that one inherits from one's parents, in contrast to acquired immunity, which one develops over the course of one's life.Acquired immunity is built up when one suffers from and beats a given illness; memory cells in the immune … Active immunity results from an infection or an immunization, while passive immunity comes from naturally or artificially gaining antibodies.

Innate immunity includes all the defence elements with which an individual is born. Humans who have already been exposed to an illness and have fought off the illness have antibodies to said illness in their blood. It determines this by the antigens, or proteins, on the cell surface. Active immunity can either be natural, such as from an infection, or artificial, such as from vaccination. Mechanical barriers: skin, mucous membranes - 1st line of defense), tears and mucus, phagocytic WBC, Inherited specific protection against certain types of invading pathogens and other toxic materials, Humans are immune against certain pathogens that affect other animals (ex: distemper virus that kills dogs), A type of immunity due to a non-deliberate exposure in the course of everyday living, Develops when the body's immune system responded to a harmful pathogen (ex: immunity from measles infection), Immunity acquired from another immune individual (ex: antibodies from the mother transferred via placenta or milk), A type of immunity acquired after the body has been deliberately exposed to a potentially harmful agent, Immunoglobulin injections (boosts the immune system), A protein substance produced by the body that destroys or inactivates a specific foreign substance called antigen, A substance that when introduced into the body causes formation of antibodies, IgG (immunoglobulin G), IgM, IgA, IgE, IgD, The smallest and works by coating the bacteria to facilitate phagocytosis; targets pathogenic organisms such as bacteria, viruses and parasitic worms, attach to antigen on one end and the other to a phagocyte white cell which absorbs and destroys the antigen.
