Jan 17, 2022 · Fig 3 – Graph showing the immune response in the body following vaccination and reinfection – the response is much faster on reinfection due to B and T cell memory cells in the immune system. Immune memory describes the ability of the immune system to recognise and rapidly respond on re-exposure to specific antigens.

In this explainer, we will learn how to compare the primary and secondary antibody responses to infection and explain the role of memory cells in the secondary response. Newborn babies and small children are generally more susceptible to illness than healthy adults.

Innate immune responses are activated rapidly but do not hold a molecular memory. T and B lymphocytes (T and B cells) are part of the adaptive immune system. Adaptive immunity retains memory, providing protection against subsequent insult by the same pathogen.

Jun 15, 2021 · Compare and contrast the innate and adaptive immune responses, and explain how they interact. Explain the role of memory cells when the body responds to a pathogen it has previously encountered, and apply this knowledge to the function of vaccines. Interpret graphs to support and/or revise scientific explanations.

The ways in which immunity is gained can be classified as active or passive immunity, and then further as artificially or naturally acquired. Active immunity is when the body responds to a pathogen using the adaptive immune response and memory cells are formed.

Our adaptive immune system is often described in two divisions, humoral immunity and cell-mediated immunity. A graph showing the progress of a complete primary immune response is shown in Figure 1.

Dec 27, 2024 · The targeting and destruction of intracellular pathogens by T cells is called cell-mediated immunity, or cellular immunity. Figure \(\PageIndex{1}\): This graph illustrates the primary and secondary immune responses related to antibody production after an initial and secondary exposure to an antigen.

Feb 11, 2025 · Explore the intricate components and interactions of the immune system with a detailed diagram and insightful analysis. Understanding the immune system is crucial as it plays a vital role in defending the body against infections and diseases. This complex network of cells, tissues, and organs works to identify and neutralize harmful pathogens.
