Answer

At the arterial end of the capillaries. Explanation 1. Understand Hydrostatic and Osmotic Pressure Hydrostatic pressure is the force exerted by a fluid due to gravity, while osmotic pressure is the force required to prevent water from moving across a semipermeable membrane. 2. Analyze Capillary Dynamics At the arterial end of capillaries, hydrostatic pressure is typically greater than osmotic pressure, facilitating filtration out of the capillaries.
