Tissue fluid is formed because of the high hydrostatic pressure of the blood at the arteriole end of the capillary that pushes fluid out of the blood. The blood contains plasma proteins giving the blood a relatively high solute potential (and therefore a low water potential), tending to draw water into the blood.lood consists of cells bathed in a liquid plasma. When this plasma leaks out of the capillaries, it is called tissue fluid. This is almost identical in composition to plasma but contains less protein molecules and no red blood cells.

1 The estrus cycle lasts on average 12-21 days, but maybe be as short as a few days to four weeks. 2  The estrus period length varies widely between breeds and individual dogs. 3  The length of a cycle varies widely, even for dogs of the same breed. 4  If in doubt, assume the longer end of the range for the cycle length.
