Glomerular Filtration and Renal Function

Renal fraction can be described as the percentage of cardiac output that is received by the kidneys.

• true

• false

filtration fraction is the percentage of plasma that will become filtrate. what percentage of plasma is generally pushed out to enter bowman's capsule?

• about 50%

• about 10%

• about 20%

• about 30%

What is the difference across the glomerular capillary wall?

• net filtration pressure

• glomerular filtration rate

• intrinsic control

• extrinsic control

• two of these are correct

match the following.

• capsular hydrostatic pressure

• the pressure of the capsular space resulting from the “traffic jam” from the accumulation of filtrate

• glomerular hydrostatic pressure

• the pressure of the proteins that pulls inward to the capillary

• glomerular osmotic pressure

• the pressure of the glomerular capillary pushing a percentage of the blood outward to bowman’s capsule

match the following

• • about 30 mmHg

• • glomerular osmotic pressure

• • about 55 mmHg

• • glomerular hydrostatic pressure

• • about 7-10 mmHg

• • net filtration pressure

• about 15 mmHg

• • capsular hydrostatic pressure

the glomerular capillary and blood capillaries found throughout the body function similarly in that they both deliver and pick up wastes and nutrients.

• true

• false

NGSS.HS-LS2-3

filtrate is essentially the same composition as which of the following, minus the larger molecules found in this fluid-

• intracellular fluid

• intracellular fluid

• plasma and intracellular fluid

• extracellular fluid and intracellular fluid

• plasma

through which vessel does blood arrive to the glomerular capillary?

• the glomerular capillary itself

• the afferent arteriole

• the efferent arteriole

• both the afferent and efferent arteriole

• it depends

which of the following is too large to pass through the capillary wall to become part of the filtrate?

• proteins

• blood cells

• both of these are correct

• neither of these is correct

which of the following structures serves to "catch" filtrate pushed out of the blood and guide it to the nephron loops?

• the glomerular capillary

• loop of henle

• efferent arteriole

• bowman's capsule
