Question

The cell-mediated immunity inside the human body is carried out by

• A. T- lymphocytes
• B. B-lymphocytes
• C. Thrombocytes
• D. Erythrocytes

Answer 1

The correct option is A T- lymphocytes

Acquired immunity creates an immunological memory after an initial response to a specific type of pathogen and leads to an enhanced response when an encountering with that pathogen.

The acquired immune system includes both humoral immunity component, cell-mediated immunity.

Humoral immunity is mediated by macromolecules found in extracellular fluids such as antibodies. Antibodies are formed by a specific type of cells called B lymphocytes.

Cell-mediated immunity is an immune response that does not involve the antibodies, but rather than involves the activation of antigen-specific T-lymphocytes.

So, the correct answer is 'T- lymphocytes'
