In adaptive (specific) immunity, which blood cells are primarily responsible for recognizing specific antigens and mounting targeted immune responses?

• A. Erythrocytes (red blood cells)
• B. Lymphocytes (B cells and T cells)
• C. Neutrophils
• D. Platelets (thrombocytes)

Answer: (B)

Verified step by step guidance

1. Understand that adaptive (specific) immunity refers to the immune system's ability to recognize and remember specific pathogens, leading to a targeted response upon subsequent exposures.
2. Identify the types of blood cells involved in immune responses: erythrocytes (red blood cells), neutrophils, platelets, and lymphocytes.
3. Recall that erythrocytes primarily transport oxygen and do not participate in immune recognition or response.
4. Recognize that neutrophils are part of the innate immune system and respond quickly but non-specifically to pathogens.
5. Focus on lymphocytes, specifically B cells and T cells, which are the primary cells responsible for recognizing specific antigens and mounting targeted adaptive immune responses.
