Which of the following is the most common kidney stone - CORRECT ANSWER -
Calcium oxalate
Because sweat is essentially a salt solution with an osmolarity lower than that of plasma, severe
sweating leads to a reduction in plasma volume and an increase in plasma osmolarity. How do
these changes affect the secretion of ADH? - CORRECT ANSWER - both the decrease in
plasma volume and the increase in osmolarity stimulate ADH secretion
The area where blood is filtered and proteins are generally separated from the plasma is -
CORRECT ANSWER - Glomerulus
The modified smooth muscle cells that secrete renin are the - CORRECT ANSWER -
Juxtaglomerular cells
Vitamin D is essential for - CORRECT ANSWER - The absorption of Ca and phosphate
from the GI tract
