Q. Which one of the following correctly explains the function of a specific part of a human nephron?
A) Afferent arteriole: Carries the blood away from the glomerulus towards renal vein
B) Podocytes: Create minute spaces (slit pores) for the filtration of blood into the Bowman's capsule
C) Henle's loop: Most reabsorption of the major substances from the glomerular filtrate
D) Distal convoluted tubule: Reabsorption of K⁺ ions into the surrounding blood capillaries
Explanation
[Solution from source] Podocytes of Bowman's capsule are arranged so that minute filtration slits (slit pores) are left between them, through which blood is filtered into the capsule. The afferent arteriole brings blood to the glomerulus, most reabsorption happens in the PCT, and the DCT secretes K⁺ rather than reabsorbing it. Answer (2).
