The following are some of the major differences between active and passive immunity. This system is responsible for protecting the body from foreign pathogens and also clearing away dead and malfunctioning cells. When considering the human anatomy and physiology, it consists of two broad arms, namely, innate immunity and adaptive immunity. Pro Lite, Vedantu A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one’s own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body. Active immunity leads to the development of immunological memory. Cellular immunity due to the T-lymphocytes.

Exposure of the body to some part of the pathogen in a vaccine such as: Deactivated toxins from a pathogen (Corynebacterium diphtheria toxin, Clostridium tetani toxin), Part of the bacterial cell (Bordetella pertussis and streptococcus pneumonia), Understanding the basic structure of an immune system, it consists of three layers of defense to protect from infection. It is developed when ready-made antibodies are inoculated from outside. For instance, a mother introduces antibodies to a fetus through the placenta and to an infant via mother’s milk.

The effect of passive immunity is immediate; however, it takes time for active immunity to do its job in fighting off infection. Passive immunity is mediated by the antibodies produced outside. Innate immunity is non-specific and is present before birth. Class-12-science » Biology. Received from an outside source. Active vs Passive Immunity . Eg: Skin is a physical barrier as well as chemical and biological barrier as it produces antimicrobial proteins; Surface lining of the respiratory system has cilia for preventing pathogens and building up of microorganisms; Stomach release strong acids with low pH and kills microorganisms that we accidentally ingest while eating; tears also is an example of barrier immunity as it protects our eyes from dust and pathogens. So, for example the natural form of passive immunity is antibodies transferred in breast milk as mentioned, however an artificial form of passive immunity is the use of antidotes such as that for rabies where specific antibodies are injected into an infected individual. It lasts for few days. When an immune system is activated without a real danger or is not turned off when a threat passes, problems arise such as allergic reactions and autoimmune disease. well represented with exact points, easy to grasp, Your email address will not be published.

It may consist of certain side-effects when it is given externally. What is one reason why active immunity is more advantageous than passive immunity? The second line of defence is through phagocytes; this is again produced by innate immunity. It is a specific immune system that consists of highly specialised systemic cells and processes that eliminate pathogens and prevent its growth. It provides immediate protection but doesn’t guarantee long-term protection like active immunity. Passive immunity is acquired when antibodies are introduced into the body from an external source (usually through vaccines) . Learn vocabulary, terms, and more with flashcards, games, and other study tools. Antigen-specific antibodies are produced on the second exposure.
