Summary
This document is a presentation on renal physiology, covering kidney anatomy, renal blood flow, and urine formation. It explores the structure of the nephron, tubular reabsorption, and important concepts like the glomerular filtration rate. The document also touches on acid-base balance and renal failure.

Renal Physiology Prepared by Dr. Asmaa Tarek Lecturer of physiology Ain Shams University Anatomy of the kidney: The kidneys are paired organs that lays in the posterior abdominal wall. One on each side of the vertebral column. Each kidney is formed of cortex and medulla. Medulla is formed of pyramids. The structure unit of the kidney is nephrons. What is the Renal blood flow and glomerular filtration rate? RBF: is the amount of blood that enter both kidneys per unit time. Normal RBF= 1200 ml/min. GFR: is the volume of fluid filtered from glomerular capillaries per unit time by all nephrons in both kidneys. Normal GFR= 125 ml/ min. Renal Circulation Structure of the nephron Urine formation Urine formation Acid base balance and its disturbance Normal pH=7.4 Abnormality is due to a. Acidosis: pH < 7.4 Metabolic acidosis * as diarrhea, renal failure. Respiratory acidosis * as lung disease. b. Alkalosis: pH >7.4 Respiratory alkalosis * as hyperventilation. Metabolic alkalosis *as vomiting. Renal Failure
