MICROANATOMY

Detailed explanation-1: -Also called lymph gland. Anatomy of the lymph system, showing the lymph vessels and lymph organs including lymph nodes, tonsils, thymus, spleen, and bone marrow. Lymph (clear fluid) and lymphocytes travel through the lymph vessels and into the lymph nodes where the lymphocytes destroy harmful substances.

Detailed explanation-2: -Majority of the lymphocytes enter the lymph nodes via specialised vessels called high endothelial venules (HEV). The remaining lymphocytes (15–20%), together with dendritic cells and antigens, enter the lymph nodes via afferent lymphatics. Lymphocytes leave the lymph nodes via efferent lymphatics.

Detailed explanation-3: -Lymph nodes contain lots of white blood cells called lymphocytes. If you have an infection, the lymphocytes multiply inside your lymph nodes. They help fight the infection and make chemicals that activate other parts of your immune system.
