Question

what substances would you expect to find in the blood but not in the tubular fluid? (select all that apply)
check all that apply
□ water
□ blood cells
□ large plasma proteins
□ excess salts

Explanation:

To determine substances in blood but not tubular fluid, we analyze each option:

• Water: Present in both blood and tubular fluid (filtered and reabsorbed), so not correct.
• Blood cells: Too large to pass through glomerular filtration, so in blood but not tubular fluid.
• Large plasma proteins: Also too large for glomerular filtration, so in blood but not tubular fluid.
• Excess salts: Filtered and can be in tubular fluid (excreted if not reabsorbed), so not correct.

Answer:

B. Blood cells, C. Large plasma proteins
