Question: Differentiate between two types of nephrons found in kidneys

Answer:

There are two types of nephrons found in kidneys: cortical nephrons and juxtamedullary nephrons . Both cortical nephron and juxtamedullary nephron consist of the renal corpuscle, renal tubule, and the associated capillary network. Both nephrons filter blood to produce urine.

Difference Between Cortical and Juxtamedullary Nephron:

Cortical Nephron Juxtamedullary Nephron
Glomerulus is located in the outer part of the renal cortex Glomerulus is situated close to the corticomedullary border
Glomerulus size is small Glomerulus size is large
Loop of Henle is short, it is found extending only into the outer region of the renal medulla Loop of Henle is long, it is found extending deep into the renal medulla
Ascending limb is thick Ascending limb is thin
Vasa recta found in a small network Vasa recta found in a large network
Efferent arteriole is large in diameter Efferent arteriole is small in diameter
Rate of filtration slow Rate of filtration High
Functions in urinary excretion Concentrate or dilute urine
About 85% of the total nephron in the human kidney Only 15% of the nephrons in the human kidney
