Which renal structure is responsible for producing hypertonic urine by reabsorbing water while allowing metabolic wastes and NaCl to pass through?

A) Glomerulus
B) Proximal convoluted tubule
C) Distal convoluted tubule
D) Collecting duct
E) Nephron loop

Hypertonic Urine

Urine that has a higher osmotic pressure than the surrounding fluids, indicating a high concentration of solutes.

Collecting Duct

The tubule segment in the kidneys that receives urine from multiple nephrons and transports it to the renal pelvis, playing a key role in the body's ability to concentrate urine.

Metabolic Wastes

Byproducts produced from the body’s metabolic processes, which need to be excreted to maintain homeostasis.
