Q

Formation of lymph fluid

A

Fluid that gets filtered out from capillaries enters the interstitial spaces. This becomes the interstitial fluid. When interstitial fluid accumulates, it is picked up by the lymphatic capillaries. Now it is called lymphatic fluid. From lymphatic capillaries, lymphatic fluid then moves into lymphatic vessels and deposits and flows through lymph tissues and then to lymph nodes, which then again empty into the blood stream.
