If you can remain in an inverted posture for just 3 to 5 minutes, the blood will not only
drain quickly to the heart, but tissue
fluids will flow more efficiently into the veins and lymph channels of the lower extremities and of the
abdominal and pelvic organs, facilitating a healthier exchange of nutrients and wastes between cells and capillaries.
If
fluids have built up in the
abdominal cavity, these will first need to to be
drained by a process known as abdominocentesis, in which a needle is inserted directly into the cavity, and excess
fluid is drawn out.
