Question

short note on lymph nodes

Answer 1

Lymph nodes are specialized masses of tissue that are situated along lymphatic system pathways. These structures filter lymph fluid before returning it to the blood. Lymph nodes, lymph vessels, and other lymphatic organs help to prevent fluid build-up in tissues, defend against infection, and maintain normal blood volume and pressure in the body. With the exception of the central nervous system (CNS), lymph nodes may be found in every area of the body.
