RENAL ANATOMY,
PHYSIOLOGY, AND
FUNCTION TESTING
CHAPTER 2
,NEPHRONS
• Functional unit of the kidney
• 1 to 1.5 million per kidney
• Two types of nephrons
• Cortical
• Removal of waste products
• Reabsorption of filtered nutrients
• Juxtamedullary
• Longer loops of Henle
• Urine concentration
,NEPHRON FUNCTIONS
• Renal blood flow
• Glomerular filtration
• Tubular reabsorption
• Tubular secretion
, RENAL BLOOD FLOW
• Afferent arteriole (renal artery)
• Blood enters the glomerulus
• Efferent arteriole
• Blood leaves the glomerulus
• Peritubular capillaries /proximal convoluted tubule
• Vasa recta/loops of Henle
• Peritubular capillaries/distal convoluted tubule
• Renal vein
