Immunity is the body’s defense system against infection. The innate immune system acts as the body’s first line of defense against disease and is implicated in a massive number of disease processes. The short answer is that immunity has two main types: innate and acquired. Innate immunity is present from birth, while acquired immunity is learned over time. Innate immunity protects the body from invaders by providing a quick response. While acquired immunity helps to build a defense livemocha system, it can sometimes fail to do its job.
Infections are the result of foreign substances, or antigens. People with certain genes may develop an allergic reaction to harmless substances found in the environment. This overactive immune system results in various symptoms. The immune system lunarstorm consists of specialized cells called T and B cells that recognize and respond to antigens. These cells are found in the body’s lymph nodes and spleen. In addition, it is also found in our mucous membrane layers.
There are two types of immunity: passive and acquired. Passive immunity, also known as acquired immunity, is produced by the body after exposure to a pathogen. While passive immunity is generated by external sources, acquired immunity is developed during life. Although people are born with some level of innate immunity, they don’t necessarily have it. Passive immunity meetro can be induced artificially through a high level of antibody serum or plasma.
