A lymph node is an oval-shaped organ of the lymphatic system, distributed widely throughout the body including the armpit and stomach and linked by lymphatic vessels. Lymph nodes are major sites of B, T, and other immune cells.ymph nodes are bean or oval shaped and range in size from a few millimeters to about 1â2 cm long.
