Question

Which one of the following correctly explains the function of a specific part of a human nephron ?

• A. Distal convoluted tubule : re-absorption of $K ^{+}$ ions into the surrounding blood capillaries
• B. Afferent arteriole : carries the blood away from the glomerulus towards renal vein
• C. Podocytes : Create minute spaces (slit pores) for the filtration of blood into the Bowman's capsule
• D. Henle's loop : most reabsorption of the major substances from the glomerular filtrate

Answer 1

Answer: (C)

Most reabsorption of the major substances from the glomerular filtrate takes place in proximal convoluted tubule. In $DCT$, selective secretion of $H^{+}$ and $K^{+}$ occur to maintain $pH$ and $Na - K$ balance in blood. Afferent arteriole carries the blood towards the glomerulus
