Document Summary

Fluid recovery: fluid continually filters from h blood capillaries into the tissue spaces, blood capillaries on average reabsorb about 85% Interference with lymphatic drainage leads to severe edema. Immunity: excess fluid removes foreign cells and chemicals from the tissues, passes through lymph nods where immune cells can activate a immune. Lymphatic vessels are arranged in a similar pattern as blood vessels. Collecting vessels: the lymphatic capillaries converge and become larger collecting vessels, which run parallel alongside veins and arteries. Six lymphatic trunks: each drain major portions of body. Two collecting ducts: one drains right side and one drains left side and below diaphragm: both ducts empty into subclavian veins. Lymphatic capillaries converge to become collecting vessels which pass through lymph nodes. Moved along by rhythmic contractions of lymphatic vessels. Thoracic pump aids flow from abdominal veins draws lymph into it. More rapidly flowing blood in subclavian veins draws lymph into it.
