DownloadWhat are the primary lymphoid organs and their functions?
Flip card
The primary lymphoid organs are the bone marrow and the thymus. The bone marrow is responsible for the production of blood cells, including B and T lymphocytes, while the thymus is where T lymphocytes mature.
Describe the role of antigen-presenting cells (APCs) in the immune response.
Flip card
APCs, such as dendritic cells, macrophages, and B cells, capture antigens and present them on their surface using MHC molecules. This presentation is crucial for the activation of T cells, which then initiate an adaptive immune response.
What is the difference between innate and adaptive immunity?
Flip card
Innate immunity is the bodys first line of defense and is non-specific, involving barriers like skin and phagocytic cells. Adaptive immunity is specific and involves lymphocytes that recognize and remember specific pathogens for a more efficient response upon re-exposure.
Explain the process of clonal selection in B cells.
Flip card
Clonal selection is the process by which a B cell with a receptor specific to an antigen is selected for proliferation. Upon binding to its specific antigen, the B cell is activated, proliferates, and differentiates into plasma cells and memory B cells.
What are the functions of helper T cells (CD4+) in the immune system?
Flip card
Helper T cells coordinate the immune response by secreting cytokines that activate other immune cells, including B cells, cytotoxic T cells, and macrophages, enhancing their ability to clear infections.
How do cytotoxic T cells (CD8+) kill infected cells?
Flip card
Cytotoxic T cells recognize infected cells through MHC class I molecules presenting viral peptides. They induce apoptosis in these cells by releasing perforin and granzymes, which create pores and trigger cell death.
Define the term immunological memory and its significance.
Flip card
Immunological memory refers to the immune systems ability to remember a previously encountered antigen, resulting in a more rapid and robust response upon subsequent exposures. This is the principle behind vaccination.
What is the role of regulatory T cells in the immune system?
Flip card
Regulatory T cells maintain immune homeostasis by suppressing immune responses, preventing autoimmunity, and ensuring that immune responses do not damage host tissues.
