MEDICAL PHYSIOLOGY

Detailed explanation-1: -The urine flows out of the nephron tubule into a collecting duct. It passes out of the kidney through the renal pelvis, into the ureter, and down to the bladder.

Detailed explanation-2: -A minor calyx surrounds the renal papillae of each pyramid and collects urine from that pyramid. Several minor calyces converge to form a major calyx. From the major calyces, the urine flows into the renal pelvis; and from there, it flows into the ureter.

Detailed explanation-3: -A minor calyx receives urine from the papillary ducts of one renal pyramid and delivers urine to a major calyx. From the major calyces, the urine drains into a large cavity called the renal pelvis and then out through the ureter to the urinary bladder.
