When used in the context of exercising When you exercising, your heart is pumping large amount of blood to the working muscles. This blood is carrying both oxygen and nutrients to the muscles and then returns to the heart for oxygen. However, when the exercise stops, so does the force that pushes the blood back to the heart. If you don't cool down lactic acid stays in the muscles, which in turn causes swelling and pain. This is known as 'blood pooling" Cooling down keeps the blood circulating, which in turn helps to prevent blood pooling and also removes waste products from the muscles.
Pooling of blood in the extremities is "hypostasis", the effect of gravity bringing blood to the lowest positional regions (either of an organ or the body as a whole). For post-mortem examinations, "lividity" (livor mortis) is the discoloration caused by blood pooled immediately after death.
