Learning with Dr. Umema Zafar
Renal Physiology From Scratch
A clear, step-by-step route from body fluids to acid–base balance—designed to help health-sciences students connect mechanisms with clinical reasoning.
Official previews, current pricing and enrollment are provided securely on Udemy.
01 / The approach
Understand the system. Then solve the problem.
Renal physiology becomes easier when fluid balance, filtration, tubular function, electrolytes and acid–base control are learned as parts of one system. The course develops those connections with practical examples and clinical scenarios.
The course map
Six connected foundations
Move from core concepts to high-yield mechanisms and clinical application at a measured pace.
- 01
Body fluids
Compartments, osmosis, tonicity, fluid shifts, edema and dehydration.
- 02
Renal anatomy & GFR
Urine formation, micturition, renal circulation and filtration.
- 03
Tubular transport
Reabsorption, secretion, clearance and hormonal control.
- 04
Urine concentration
ADH, dilution, countercurrent mechanisms and osmolarity.
- 05
Electrolyte balance
Potassium, calcium, phosphate, magnesium and sodium regulation.
- 06
Acid–base balance
Buffers, compensation, ABG interpretation and clinical vignettes.
