Web8 jun. 2024 · Blood Pressure. Blood pressure is the pressure of the fluid (blood) against the walls of the blood vessels. Fluid will move from areas of high to low hydrostatic pressures. In the arteries, the hydrostatic pressure near the heart is very high. Blood flows to the arterioles (smaller arteries) where the rate of flow is slowed by the narrow ... WebEffects. Hydrostatic pressure is a steady volume force that applies a net force on an object or surface, while osmotic pressure is a variable volume force that applies a net force on an object or surface. Hydrostatic pressure forces are applied in a fixed volume as it is measured and osmotic pressure forces are applied over a variable volume.
