Humoral immune response is performed by:

Options

A. Lymph nodes
B. B-lymphocytes
C. T-lymphocytes
D. Spleen

Answer

**Step-by-Step Text Solution:**

1. **Understanding Humoral Immune Response**: The humoral immune response is a part of the adaptive immune system that involves the production of antibodies. The term "humoral" refers to the body fluids where these antibodies are found.

2. **Role of B-Cells**: The primary cells responsible for the humoral immune response are B-lymphocytes (B-cells). When B-cells encounter an antigen (a foreign substance), they become activated.

3. **Activation of B-Cells**: Upon activation, B-cells differentiate into plasma cells. This process is often aided by signals from T-helper cells, which are a subtype of T-lymphocytes.

4. **Production of Antibodies**: The plasma cells that B-cells become are responsible for producing antibodies. These antibodies are specific to the antigens they are designed to neutralize or mark for destruction.

5. **Conclusion**: Therefore, the humoral immune response is primarily performed by B-lymphocytes, which produce antibodies in response to antigens.

**Final Answer**: The humoral immune response is performed by B-lymphocytes (B-cells).
