Hydrostatic pressure is high at the arterial end of a blood capillary because this is where blood enters the capillary under high pressure from the heart. This pressure helps to push fluid and nutrients out of the capillary and into the surrounding tissues. This process is essential for delivering oxygen and nutrients to cells and removing waste products.
