Measure the diameters of afferent arteriole and efferent arteriole ?

The diameter of the afferent arteriole is typically larger than that of the efferent arteriole. The afferent arteriole has a diameter of around 30-40 micrometers, while the efferent arteriole has a diameter of around 20-30 micrometers. These diameters can vary slightly depending on the specific location in the body and individual variations.

Afferent arteriole: 13-19 μm
Efferent arteriole: 12-16 μm
