White blood cells, or leukocytes. The two basic types of leukocytes are: # phagocytes, cells that destroy invading organisms. # lymphocytes, cells cause the body to remember and recognize previous invaders and help the body destroy them.
The recognition of an antigen by a naive T or B cell is the most important event in establishing a primary immune response. This recognition leads to activation and proliferation of these cells, resulting in the generation of specific immune responses to combat the antigen.
The activation of the inflammatory response is typically triggered by the recognition of pathogens or tissue damage by the immune system. This recognition leads to the release of inflammatory mediators such as cytokines and chemokines, which promote inflammation by recruiting immune cells to the site of infection or injury.
There are two immunoglobulins in exocrine secretions: lgA & lgE
Memory cells arise from B cells and T cells following a primary immune response. When these lymphocytes encounter their specific antigen, they undergo clonal expansion and differentiation, resulting in the formation of effector cells and a subset of long-lived memory cells. These memory cells persist in the body and enable a quicker and more robust response upon subsequent exposures to the same antigen.
The secondary response to invasion by the same microbe is more rapid and robust due to memory T and B cells that were generated during the primary response. This leads to a quicker and more effective elimination of the invading microbe, providing long-lasting immunity against future infections by the same microbe.
Memory cell. Memory cells are a type of immune cell that remember specific antigens upon initial exposure, allowing for a faster and more effective response upon subsequent exposure to the same antigen.
an allergic reaction
Secondary Immune Response is more rapid.
Memory B cells are a characteristic part of the secondary immune response. They are formed during the primary immune response and can quickly recognize and respond to a previously encountered antigen by producing antibodies. This results in a faster and more robust immune response upon subsequent exposure to the same antigen.

ACKNOWLEDGEMENT - a recognition or response
Lack of memory B cells for a specific antigen would primarily impact the secondary humoral response. Memory B cells play a critical role in mounting a more rapid and robust immune response upon re-exposure to the antigen during a secondary response.
A secondary hazard refers to a risk or danger that arises as a consequence of a primary hazard. For example, an earthquake (primary hazard) can lead to secondary hazards such as landslides, tsunamis, or fires resulting from ruptured gas lines. These secondary hazards can exacerbate the impact of the initial event, leading to greater damage and increased risk to life and property. Understanding secondary hazards is crucial for effective disaster preparedness and response.
Well...
when it an infection or something gets past the first immune response then your body uses a different response or after immunisation
It depends on which responses you are talking about. In the autonomic system of the body that protects if from harm, the first response is quicker and the secondary response is more robust, and that is because it takes longer to involve more systems in the body to be called into action.
i am asking, if i knew i would not ask
