Lymphatic system
About this unit
Your heart pumps about 20 L of blood a day through your body. The plasma component of blood leaks out through capillaries and is mostly reabsorbed. However, about 3 L of the plasma is left behind in fluid surrounding tissues, and it is the job of the hard-working lymphatic system to bring back this fluid to the circulatory system.
