Lymph Nodes

Blood vessels and lymph vessels are present within the bladder. Lymph vessels carry lymph fluid, a colorless and watery liquid, between lymph nodes. Lymph nodes are small, bean-shaped structures throughout the body. They filter lymph fluid and store white blood cells that fight infection and disease. Lymph nodes in the bladder are found between the bifurcation of the common iliac arteries and the inguinal ligament.
