1

a. The capillary endothelium, basement membrane and juxtaglomerlar apparatus
b. Capillary endothelium, podocytes, and basement membrane
c. Podocytes, Hilum, and basement membrane
d. Capillary endothelium, podocytes, and juxtaglomerular

B

There are 3 major components of glomerular capillary wall accounting for the
glomerular filtration (inside to out): Endothelial cells with fenestra, glomerular
basement membrane (GBM), and Visceral epithelial cells (podocytes)

2

The glucose renal threshold is 160-180mg/dL. This represents the:
a. Concentration of glucose in the vasa-recta
b. Maximum range of glucose reabsorption in the renal tubule
c. Plasma concentration below which glucose is reabsorbed in the urine
d. Plasma level at the commencement of glucose reabsorption in the nephron

B

Threshold substance: almost completely reabsorbed by the renal tubules
except when normal plasma level is exceeded.
Glucose: high threshold substance, appears in urine when plasma
concentration exceeds about 160 to 180 mg/dL

3

Aldosterone is involved in ____ reabsorption and is released by the ____ of the
adrenal cortex
a. potassium/zona glomerulosa
b. sodium / zona fasiculata
c. potassium / zona fasiculata
d. Sodium / zona glomerulosa

D

Aldosterone: secreted by the adrenal cortex (zona glomerulosa). Enhances
potassium ions/ sodium ion exchange in distal tubules of nephron. Increased
blood sodium, which in turn increases body water as water follows salt, raising
blood pressure. Release is triggered by angiotensin II, could contribute to
hypertension

the body cannot get enough glucose for energy it will switch to using body fats,
resulting in a increase production of making them detectable in the blood and
urine
