So it's the same here as it is the same on the other side, the manual side of our capillary. Now, the question is, how exactly do these two different pressures influence the movement of our blood plasma across the wall of the capillary? Well, to find the net pressure and the net fluid flow, we have to basically add up these two different pressures. So let's begin on the arterial end, of the capillary. We know that the hydrostatic pressure points outward, but the osmotic pressure points inward. So they point in opposite directions.
