What is the Urine-Making Structure of the Kidney

Question

What is the urine-making structure of the kidney?
A) Trigone
B) Renal pyramid
C) Renal capsule
D) Nephron unit

Accepted Answer

The nephron unit is the urine-making structure of the kidney. Each kidney contains about a million nephrons, which are microscopic structures responsible for filtering the blood and producing urine. The other options listed (trigone, renal pyramid, renal capsule) are structures within the kidney but not directly involved in urine formation.
