Definition secondary immune response
The initial encounter of a nave immunecompetent lymphocyte with an antigen induces a primary immune response; a later contact of the host with the same antigen will induce a more rapid and heightened secondary immune response.Immune responses to antigens may be categorised as primary or secondary responses. The primary immune response of the body to antigen occurs on the first occasion it is encountered. Depending on the nature of the antigen and the site of entry this response can take up to 14 days to resolve and leads to the generation of memory cells with a high specificity for the inducing antigen. definition secondary immune response
Secondary Immune Response: Secondary immune response refers to any immune response of the immune system that occurs in response to the subsequent exposure to a particular antigen. Occurrence Primary Immune Response: Primary immune response occurs in

Oct 10, 2015 Primary immune response: Secondary immune response: 1. This occurs as a result of primary contact with an antigen. This occurs as a result of second and subsequent exposure of the same antigen: 2: Responding cell is nave Bcell and Tcell. Responding cell is memory cell. 3: Lag phase is often longer (47 days), sometimes as long as weeks or months.
The immune system is located all over the body in order to provide quick immune responses wherever infection occurs. The immune cells travel through blood and lymphatic system vessels. Our immune system has primary immune response as well as secondary response.

Response of the body to an antigen with which it has already been primed see primary immune response. There is a very rapid production of large amounts of antibody over a few days, followed by a slow exponential fall.
The Immune response is the body's response caused by its immune system being activated by antigens. The immune response can include immunity to pathogenic microorganisms and its products, as well as autoimmunity to selfantigens, allergies, and graft rejections.
The response of the immune system to an antigen (immunogen) that leads to the condition of induced sensitivity; the immune response to the initial antigenic exposure (primary immune response) is detectable, as a rule, only after a lag period of from several days to 2 weeks; the immune response to a subsequent stimulus (secondary immune response) by the same antigen is more rapid than in the
