IMMUNOLOGY

Detailed explanation-1: -Lymphatic vessels collect and filter lymph (at the nodes) as it continues to move toward larger vessels called collecting ducts. These vessels operate very much like your veins do: They work under very low pressure, have a series of valves in them to keep the fluid moving in one direction.

Detailed explanation-2: -Lymphatic capillaries are tiny vessels found in the tissues of most organs in your body. They transport and filter lymphatic fluid (lymph) from your body’s cells and tissues. Lymph capillaries help to keep consistent blood pressure and volume and prevent fluid buildup.

Detailed explanation-3: -Fluid that is forced out of the bloodstream during normal circulation is filtered through lymph nodes to remove bacteria, abnormal cells and other matter. This fluid is then transported back into the bloodstream via the lymph vessels. Lymph only moves in one direction, toward the heart.
