Lymph Nodes

Blood vessels and lymph vessels are present within the prostate. 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.
