Lymphatic System & Fluid Balance: Understanding Fluid Return

No, it is not true.

Explanation:

The volume of fluid filtered from the capillaries each day is about 20 liters, and all but about 3 liters of this is returned directly to the blood by the small venules. The 3 liters that do not return directly to the blood are returned via the lymphatic system, which is why the lymphatic system sometimes is called a third circulation, in addition to the pulmonary and systemic circulations.
