<prompt> The rate of lymph flow is:10 mlhr20 mlhr50 mlhr120 mlhr  <response>: Rate of lymph flow is 2 mlmin or 120 mlhr or 2 to 4 liters per day. Lymphatic system provides an accessory route by which interstitial fluid drains into the blood. Lymph from all over is emptied into the thoracic duct which then drains the lymph into the venous system at the junction of the left internal jugular vein IJV and subclan vein. Lymph composition is similar to interstitial fluid; protein concentration of lymph in most tissues 2 gm, lymph coming from the liver has 6 gm of proteins. Factors increasing lymph flow: Contraction of surrounding skeletal muscles, movements of the body pas, pulsations of the neighboring aeries, objects compressing the tissues from outside the body.
