  • Q1 · Excretion and Osmoregulation (Class 11 — ~20% weight) · EASY

    In the process of urine formation, the glomerular filtrate has a composition similar to blood plasma except for the absence of which component?

  • Q2 · Excretion and Osmoregulation (Class 11 — ~20% weight) · MEDIUM

    Which part of the nephron is primarily responsible for the reabsorption of approximately 65% of the glomerular filtrate, including glucose, amino acids, and most of the water and sodium ions?

  • Q3 · Excretion and Osmoregulation (Class 11 — ~20% weight) · HARD

    A patient with chronic kidney failure undergoes hemodialysis. The dialysis fluid used must have a specific composition to ensure proper functioning. If the dialysis fluid contains glucose at 100 mg/dL and the patient's blood glucose is 180 mg/dL, and the dialysis fluid has no urea while the patient's blood urea is 80 mg/dL, which of the following best explains the outcome after dialysis?
