Where is the kidney located?
-
Glomerulus Capillary system
- a high-pressure capillary filtration system located between the afferent and efferent arterioles
-
Peritubular Capillary System
- a low-pressure reabsorptive system that originates from the efferent arteriole

a) antiport
b) sypmort
c) Exchange
-
a
Moving two or more ions in opposite directions.
a) antiport
b) sypmort
c) Exchange
-
the cells exchange 3 sodium ions for 2 potassium ions
What does "exchange" mean?
-
increase; increase
Vasodilation of the afferent arteriole will lead to a _______ in blood flow and
______ in glomerular blood pressure.
-
decrease; increase
Vasoconstriction of the afferent arteriole will lead to a _________ in blood flow and ___________ in glomerular blood pressure.
