What are lymph nodes? & its importance
Lymph is a watery fluid that circulates within the lymphatic vessels. Lymph nodes are found near these vessels.Within the capsule, lymph nodes contain certain kinds of immune cells. These cells are mainly lymphocytes, which produce proteins that capture and fight viruses and other microbes, and macrophages, which destroy and remove the captured material.
Lymph nodes are an important component of the body's immune system and help in fighting infections. Infections caused by swollen lymph nodes is referred to as lymphadenitis.
Lymph nodes (sometimes called lymph glands) are small, soft, round or oval structures that are found throughout the body and are connected to each other in chain-like (lymphatic chains) fashion by channels similar to blood vessels. Each individual lymph node is covered by a capsule made up of connective tissue.
