Q1 · Measuring GFR
NEET PGMediumExplanation
Inulin is freely filtered and neither reabsorbed nor secreted, so its clearance equals GFR. Clinically creatinine clearance is used as an approximation, while PAH clearance estimates renal plasma flow.
Q2 · Renal Autoregulation
HardExplanation
Efferent arteriolar constriction raises glomerular capillary hydrostatic pressure, increasing GFR up to a point. This is why angiotensin II supports GFR in low-flow states, and why ACE inhibitors can reduce it.
Q3 · Tubular Reabsorption
NEET PGEasyExplanation
The proximal convoluted tubule reabsorbs nearly all filtered glucose and amino acids and about two-thirds of sodium and water. Glucose appears in urine only when the reabsorptive transport maximum is exceeded.
Q4 · Antidiuretic Hormone
NEET PGMediumExplanation
ADH, or vasopressin, acts on V2 receptors to insert aquaporin-2 water channels into the collecting duct's apical membrane, increasing water reabsorption and concentrating urine.
Q5 · Acid-Base Balance
HardExplanation
A low pH with low bicarbonate indicates metabolic acidosis, and the low PaCO2 shows respiratory compensation through hyperventilation. Causes include diabetic ketoacidosis, lactic acidosis and renal failure.
Q6 · Counter-current Mechanism
MediumExplanation
The loop of Henle acts as a counter-current multiplier, creating a hypertonic medullary interstitium. The vasa recta act as counter-current exchangers to preserve this gradient, enabling urine concentration.
Renal sits within Physiology, which carries the same syllabus in both exams. This set runs to 6 questions, each tagged Easy, Medium or Hard, 2 of them at Hard, and 3 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Renal marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Physiology examiners keep returning to.
FAQ
Yes. Every question and explanation in this Renal set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Renal sits within Physiology, which appears in the same form in both syllabuses. System-wise physiology with the mechanisms examiners test most: cardiac and respiratory regulation, renal handling, endocrine axes and nerve conduction.
