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 |
