And this is where the movement actually takes place. Now, we know that capillaries actually connect our arterioles to our vanills. So this is the arterial side of the capillary and this is the Venuel side of the capillary. Now, recall in our discussion on the circulation system, we said that it's the heart that actually creates the hydrostatic pressure. And it allows the movement of fluid of blood plasma inside our blood vessels. And because the arterial end of the capillary is closer to the heart than the Venuel end of the capillary, what that means is the arterial end of the capillary will have a greater hydrostatic pressure than the Venuel side.
