In the kidney, which structure empties urine into the renal pelvis?
A
Glomerulus
B
Major calyx
C
Renal corpuscle
D
Proximal convoluted tubule
Verified step by step guidance1
Step 1: Understand the flow of urine through the kidney structures. Urine is formed in the nephrons and then collected into larger structures before reaching the renal pelvis.
Step 2: Recall that the glomerulus and renal corpuscle are involved in the filtration of blood, not in collecting or transporting urine.
Step 3: Recognize that the proximal convoluted tubule is part of the nephron where reabsorption occurs, but it does not directly empty urine into the renal pelvis.
Step 4: Identify the calyces (minor and major) as the structures that collect urine from the collecting ducts and funnel it into the renal pelvis.
Step 5: Conclude that the major calyx is the structure that empties urine into the renal pelvis, acting as a funnel for urine collected from the minor calyces.
