The collecting system of the kidney consists of all of the following except renal pelvis minor calyces major calyces renal pyramids proximal ureter

Understanding the Kidney Collecting System

The collecting system of the kidney is responsible for collecting urine from the nephrons and transporting it to the bladder. The main components that make up this system include:

1. Renal Pelvis: The funnel-shaped structure that collects urine from the major calyces and channels it into the ureter.
2. Minor Calyces: These are small cup-like structures that collect urine from the renal pyramids and drain into the major calyces.
3. Major Calyces: Larger cup-like structures that receive urine from the minor calyces and funnel it into the renal pelvis.
4. Renal Pyramids: These structures contain the nephrons and are involved in urine formation, but they are not part of the collecting system itself.

The Incorrect Option

• Proximal Ureter: This is actually part of the urinary tract that transports urine from the renal pelvis to the bladder, not a component of the kidney's collecting system.

Final Answer

The collecting system of the kidney consists of all of the following except proximal ureter.
