Renal Physiology From Scratch

Renal physiology is one of the most challenging — and most high-yield — topics in health sciences education. Whether you are an MBBS or medical student working through Guyton physiology, a nursing or pharmacy student preparing for clinical practice, or a candidate studying for USMLE Step 1, this course gives you a clear, logical, step-by-step path through kidney physiology.You will build a deep understanding of nephron function, glomerular filtration rate (GFR), tubular transport, ADH and urine concentration mechanisms, electrolyte balance, and acid-base balance — including how to interpret arterial blood gases (ABG interpretation) in real clinical scenarios. Rather than memorising isolated facts, you will learn how the kidney regulates the body's internal environment as a whole system.We begin with body fluid compartments, osmosis, tonicity, edema, dehydration, and overhydration, then move into renal anatomy, urine formation, micturition, and the forces that determine glomerular filtration rate. You will then explore tubular transport, clearance, glomerulotubular balance, countercurrent mechanisms, ADH, free water clearance, potassium, calcium, phosphate, magnesium, sodium balance, pressure diuresis, and natriuresis. The course also guides you through acid-base physiology, buffer systems, compensation, arterial blood gas interpretation, and the clinical impact of diuretics. With practical examples and real-world scenarios such as electrolyte imbalance, diabetes insipidus, acidosis, and alkalosis, this course helps you connect physiology with patient care. Each topic is explained step by step so you can build strong concepts, solve exam questions, and approach clinical problems more confidently. Whether you are a medical, dental, pharmacy, nursing, or allied health sciences student, this course will help you master renal physiology with confidence
