1) What is the primary driving force behind the movement of fluid during filtration? a) Concentration gradient b) Hydrostatic pressure difference c) ATP energy expenditure d) Electrical gradient 2) Which of the following conditions would likely increase the movement of fluid out of the blood and into the glomerular capsule during filtration? a) Increased blood pressure b) Decreased glomerular capillary permeability c) Low blood pressure d) Reduced surface area of the filtration membrane 3) In capillary filtration outside the kidneys, such as in peripheral tissues, fluid moves out of the capillaries at the arterial end due to: a) High osmotic pressure in the capillaries b) Higher hydrostatic pressure at the arterial end of capillaries c) Low concentration of plasma proteins in the capillaries d) High ATP levels in the surrounding cells 4) The movement of fluid back into capillaries at the venous end, opposing filtration, is primarily driven by: a) Oncotic pressure exerted by plasma proteins in the blood b) Hydrostatic pressure in the interstitial fluid c) High blood pressure in the venous capillaries d) Concentration gradients of electrolytes
