a: lymphatic system ~
b: a garbage disposal


"The human body has 600 to 700 oval shaped lymph nodes that range in size from 1/16 of an inch to one inch. These lymph nodes filter and purify the fluid that flows through them, rendering bacteria and viruses harmless. The lymph vessels leading to the nodes are a complex network of channels with one-way valves. They remove metabolic wastes, excess water, toxins and foreign substances from the connective tissue. Ultimately, the fluid that is processed by the lymphatic system returns to the blood stream. The lymphatic system moves and processes two to four liters of lymph in a 24-hour period. The lymphatic system is like a garbage disposal for the human body. The lymph system is divided into quadrants such as the leg and pelvis or the arm and chest. Each quadrant has a basin of lymph node chains that become interim draining points en route to the final draining point in veins at the neck. The areas in the body with the highest concentration of lymph nodes are the neck, the armpits (axillary), the groin (inguinal) and the abdomen. "
