The defence mechanisms of the body are complex and include innate (non-specific, non-adaptive) mec The resistance that an individual acquires during life by recognising and selectively eliminating specific foreign molecules is known as acquired immunity..

What is immunity . Immunity is the ability of the body to defend itself against disease-causing organisms. Everyday our body comes in contact with several pathogens, but only a few results into diseases. The reason is, our body has the ability to release antibodies against these pathogens and protects the body against diseases. This defense mechanism is called Immunity.. Features of adaptive immunity:. Adaptive immunity is characterized by the following:. 1. Antigenic specificity: (. highly specific).. 2. Diversity : . ( each antigen there is specific T-cell and B-cell for it)..
