ANATOMY

Detailed explanation-1: -Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. The lymph nodes act as filters. Various immune system cells trap germs in the lymph nodes and activate the creation of special antibodies in the blood.

Detailed explanation-2: -Antigen-activated B cells migrate to the medullary cords where they differentiate into antibody-producing plasma cells. Antibodies produced in the course of a humoral immune response leave the lymph node predominantly via the efferent lymphatic vessel.

Detailed explanation-3: -Inside the lymph nodes, lymphocytes called T-cells and B-cells help the body fight infection. B cells make antibodies-special proteins that stop infections from spreading by trapping disease-causing germs and destroying them. Most of our lymph nodes are in clusters in the neck, armpit, and groin area.

Detailed explanation-4: -Synthesized exclusively by B cells, antibodies are produced in billions of forms, each with a different amino acid sequence and a different antigen-binding site.
