The lymphatic system is involved with the immune and circulatory systems. It includes a network of lymph vessels and lymph nodes. It drains fluid (called lymph) that has leaked from the blood vessels into the tissues and empties it back into the bloodstream via the lymph nodes. 11. The lymphatic system is a vascular network of tubules and ducts that collect, filter, and return lymph to blood circulation. These lymph vessels connect to a group of lymph nodes. The lymphatic system is a system of capillaries, vessels, nodes and other organs that transport a fluid called lymph from the tissues as it returns to the bloodstream. Flow is controlled by the movement of the body during activity, arterial pulsation, presure changes when breathing and valves to prevent backflow. It also transports fats from the small intestine to the blood. However, unlike the cardiovascular system, the lymph drainage is a one-way flow, not a circulation. Multiple Choice Questions 1.
