What is the lymphatic system?

ANSWER

The lymphatic system is a network of nodes (knots of tissue) connected by vessels that drain fluid and waste products from the body. The lymph nodes act as tiny filters, straining out foreign organisms and cells. The lymphatic system also is involved in making white blood cells called lymphocytes that help protect you against various infections caused by bacteria, viruses, and fungi.
