Question

Which of the following accurately follows the flow of urine from a renal papilla to the urinary bladder?

Renal papilla, renal pelvis, major calyx, minor calyx, ureter, urinary bladder

Renal papilla, renal pelvis, minor calyx, major calyx, ureter, urinary bladder

Renal papilla, major calyx, minor calyx, renal pelvis, ureter, urinary bladder

Renal papilla, minor calyx, major calyx, renal pelvis, ureter, urinary bladder

Answer 1

The flow of urine from the renal papilla to the urinary bladder follows this sequence: Renal papilla, minor calyx, major calyx, renal pelvis, ureter, and finally the urinary bladder.

Step-by-step explanation:

The correct sequence that follows the flow of urine from the renal papilla to the urinary bladder is: Renal papilla, minor calyx, major calyx, renal pelvis, ureter, urinary bladder.

Urine starts at the renal papillae, which are the tips of the renal pyramids in the medulla of the kidney. It then flows into the minor calyces, cup-like structures that receive urine from the collecting ducts. Multiple minor calyces unite to form major calyces, which then merge to form the funnel-shaped renal pelvis at the center of the kidney. The renal pelvis narrows and continues as the ureter, a tube leading to the urinary bladder. Urine is actively propelled through the ureter by peristalsis. Finally, the ureter enters the bladder where urine is stored before excretion.
