Capitolo 16, Problema 5
Mark each statement as either true or false. Rewrite false statements to make them true by changing the underlined words.
__________ Secretion of antibodies by activated B cells is a form of cell-mediated immunity.
Guida verificata passo dopo passo1
Understand the key terms: 'cell-mediated immunity' involves immune responses that do not involve antibodies but rather the activation of phagocytes, T cells, and the release of various cytokines.
Recognize that 'Secretion of antibodies by activated B cells' refers to the production of antibodies, which is a hallmark of 'humoral immunity,' not cell-mediated immunity.
Determine the truth value of the statement: Since antibody secretion is part of humoral immunity, the original statement is false.
Rewrite the false statement by replacing 'cell-mediated immunity' with 'humoral immunity' to make it true: 'Secretion of antibodies by activated B cells is a form of humoral immunity.'
Review the corrected statement to ensure it accurately reflects immunological concepts and terminology.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Cell-Mediated Immunity
Cell-mediated immunity involves immune responses that do not rely on antibodies but instead use T cells to directly attack infected or abnormal cells. It is primarily responsible for defense against intracellular pathogens and cancer cells.

Introduction to Cells of the Immune System
Humoral Immunity
Humoral immunity is the aspect of immunity that involves the production and secretion of antibodies by activated B cells (plasma cells). These antibodies circulate in body fluids to neutralize pathogens and toxins.

05:47Introduction to Adaptive Immunity
Role of B Cells in Immunity
B cells are lymphocytes that, upon activation, differentiate into plasma cells that secrete antibodies. This antibody production is a key feature of humoral immunity, distinguishing it from cell-mediated immunity.
