Glomerular filtration is directly proportional to A. Blood cell size B. Hydrostatic pressure C. Osmotic pressure D. The patient’s fluid intakearrow_forward
- The afferent arteriole delivers blood to the (a) renal artery (b) efferent arteriole (c) renal vein (d) capillaries of the glomerulus (e) peritubular capillariesarrow_forwardWhich of the following does not contribute to the high salt concentration in the interstitial fluid of the kidney medulla? (a) active transport of sodium from the upper part of the ascending limb (b) diffusion of salt from the ascending limb of the loop of Henle (c) reabsorption of salt from various regions of Bowmans capsule (d) counterflow of fluid through the two limbs of the loop of Henle (e) diffusion of urea out of the collecting ductarrow_forward1. The outer one-third of the kidney is called the A. Medulla B. Minor calyces C. Renal pyramid D. Cortexarrow_forward
- Which of these forces opposes filtration from the glomerulus a. Plasma osmotic pressure b. Fluid pressure in Bowmans capsule c. Plasma hydrostatic pressure d. Two of the presented alternatives are correctarrow_forwardWhich of the following will decrease filtration at the glomerulus? ( check all that apply) A. Low colloid osmotic pressure B. Low capsular pressure C. A relatively large diameter of theefferent arterioles compared to theafferent arteriole. D. Increased number of podocytes at theglomerulusarrow_forwardGlomerular filtration can be increased by which of the following? A. Increasing blood flow via afferent arteriole B. Decreasing blood flow via afferent arteriole C. Decreasing arterial blood pressure D. Increasing blood flow via efferent arteriole The answer is (A) Increasing blood flow via afferent arteriole. Please explain why it is not the other options (B,C,D)arrow_forward
