Q1. What pressure drives filtration at the glomerulus?
- Colloid osmotic pressure
- Bowman’s capsule pressure
- Glomerular hydrostatic pressure
- Renal arterial pressure
Q2. Which layer of the filtration barrier prevents passage of large plasma proteins?
- Parietal layer of Bowman’s capsule
- Fenestrated endothelium
- Visceral epithelium
- Basement membrane
Q3. What is the role of podocytes in the glomerulus?
- Absorb glucose from filtrate
- Create filtration slits
- Produce erythropoietin
- Store calcium
Q4. Which region of the nephron has the highest water permeability?
- Thick ascending limb
- Proximal tubule
- Descending limb of loop of Henle
- Distal tubule
Q5. What substance is secreted by the proximal tubule to help eliminate drugs?
- Antidiuretic hormone
- Creatinine
- Aldosterone
- Para-aminohippurate (PAH)
Q6. Which ion is actively reabsorbed in the thick ascending limb of the loop of Henle?
- Phosphate
- Na⁺, K⁺, and Cl⁻
- HCO₃⁻ only
- Ca²⁺ only
Q7. How does aldosterone affect the nephron?
- Blocks bicarbonate secretion
- Decreases Na⁺ reabsorption, retains K⁺
- Inhibits water reabsorption
- Increases Na⁺ reabsorption, K⁺ secretion
Q8. Where is the juxtaglomerular apparatus located?
- In adrenal cortex
- At renal pelvis junction
- Inside the loop of Henle
- Near vascular pole of glomerulus
Q9. What is the function of macula densa cells?
- Monitor NaCl and regulate GFR
- Filter urea
- Reabsorb glucose
- Secrete ADH
Q10. Which portion of the nephron is impermeable to water but reabsorbs ions?
- Descending limb of loop of Henle
- Thick ascending limb of loop of Henle
- Collecting duct
- Bowman’s capsule
