Renal Physiology - Part 9
The kidneys are of outstanding importance. They perform a number of homeostatic functions including filtration of plasma and elimination of metabolic waste products, regulation of the composition and volume of the extracellular fluid, and regulation of blood pressure. The kidneys are also endocrine organs. Test your basic knowledge of renal physiology by taking this simple quiz.
(1)   In order for plasma to be filtered across the glomerular capillaries, the ultrafiltrate must go through all of the following physical barriers. Which barrier is thought to be the most important in determining the selectivity of the filtration process?
(2)   In the kidney glomerular capillaries, as well as in other capillaries of the body, the forces that govern filtration and absorption of fluid across the capillary wall are referred to as the __________ forces.



(3)   In a typical capillary, the net filtration pressure is positive throughout the entire length of the capillary.
(4)   In the kidney glomerular capillaries, the net filtration pressure is positive throughout the entire length of the glomerular capillary.
(5)   In a typical capillary, the colloid osmotic pressure of plasma is roughly constant throughout the entire length of the capillary.
(6)   In the kidney glomerular capillaries, the colloid osmotic pressure of plasma is roughly constant throughout the entire length of the glomerular capillary.
