What is the physiological significance of the 'arteriolar-capillary-arteriolar' arrangement in the kidney?
Show answer and explanation
Correct answer: To regulate hydrostatic pressure in the glomerulus
By having arterioles on both sides of the glomerular capillaries, the kidney can independently constrict or dilate them. This allows for precise control over the glomerular filtration rate (GFR).
