Which of the following does not normally pass from the glomerulus into Bowman's capsule during filtration?
a. glucose
b. proteins
c. sodium ions
d. urea
e. water
B; Filtration from the glomerulus involves fluid passing though the narrow spaces between glomerular endothelial cells. Typically, blood cells and proteins are retained in the blood and small soluble organic molecules (glucose and urea) and ions pass through in solution in water. During pregnancy, small amounts of proteins may pass into the urine, but any more than trace amounts is a sign of complications.
