  • These substances normally cannot pass through the filtration membrane

    A. Hemoglobin
    B. Water
    C. Sodium ions
    D. bicarbonate ions
    E. Glucose

    My best guess would be A

    By the time the filtrate reaches this, the glucose is usually completely reabsorbed.

    Ạ The end of the proximal tubule
    B. The tip of the loop of Henle
    C. The end of the distal tubule
    D. The end of the collecting duct
    E. Bowmáns capsule

  • For question number 8. I am not very sure. It says completely reabsorbed so I really doubt my answer. I think the answer is A.
