Question

In our body, antibodies are formed against pathogens in ______.

Options

• liver by RBCs

• blood by platelets

• thymus by lymphocytes

• brain by macrophages

Answer 1

In our body, antibodies are formed against pathogens in thymus by lymphocytes.

Explanation:

Antibodies are specific proteins produced by plasma cells, which are differentiated B-lymphocytes. These lymphocytes mature in lymphoid organs such as the thymus and bone marrow, and upon encountering pathogens, they produce antibodies to fight the infection. The thymus is a primary lymphoid organ involved in the development and maturation of lymphocytes, including those that eventually produce antibodies. Red blood cells, platelets, and macrophages do not produce antibodies.
