6 Immune System Quiz Flashcards
(9 cards)
What best describes the difference between the innate and adaptive immune system?
The innate immune system provides a general defense, while the adaptive immune system targets specific pathogens.
True or False: The innate immune system has a high level of specificity, similar to the adaptive immune system.
False. The innate immune system has low specificity, while the adaptive immune system has high specificity for particular antigens.
Which part of the immune system forms memory cells for a faster response upon re-exposure to the same pathogen?
Adaptive immune system
Fill in the blank: The innate immune system responds ________, while the adaptive immune system responds ________.
The innate immune system responds quickly, while the adaptive immune system responds more slowly on first exposure.
Match the anatomical barrier with its function.
Skin
Mucous membranes
Stomach acid
Cilia
Enzymes in tears and saliva
a) Traps pathogens and prevents their entry
b) Physically blocks pathogen entry
c) Kills pathogens with low pH
d) Moves trapped particles out of the respiratory tract
e) Breaks down bacterial cell walls
1 - b) Skin - Physically blocks pathogen entry
2 - a) Mucous membranes - Traps pathogens and prevents their entry
3 - c) Stomach acid - Kills pathogens with low pH
4 - d) Cilia - Moves trapped particles out of the respiratory tract
5 - e) Enzymes in tears and saliva - Breaks down bacterial cell walls
What is the primary function of cytokines in the immune response?
Act as chemical messengers that regulate immune responses
Match the term with its correct definition.
Antigen
Antibody
Epitope
a) The part of an antigen recognized by an antibody
b) A molecule that triggers an immune response
c) A protein produced by B cells that binds to specific antigens
1 - b) Antigen - A molecule that triggers an immune response
2 - c) Antibody - A protein produced by B cells that binds to specific antigens
3 - a) Epitope - The part of an antigen recognized by an antibody
Categorize the following immune cells as part of the innate or adaptive immune system: Macrophage, Natural killer (NK) cell, B cell, T cell, Mast cell, Dendritic cell, Neutrophil, Eosinophil.
Innate immune system: Macrophage, Natural killer (NK) cell, Mast cell, Dendritic cell, Neutrophil, Eosinophil
Adaptive immune system: B cell, T cell
How do antigen-presenting cells (APCs) assist in the adaptive immune response?
Antigen-presenting cells (APCs) process pathogens and display antigen fragments on major histocompatibility complex (MHC) molecules, activating T cells.
