What is minor and major calyces?

The minor and major calyces are two parts of the human kidney that play crucial roles in urine collection and elimination.

The minor calyces are small cup-like structures located in the renal pelvis of the kidney. They receive urine from the renal pyramids and transport it to the major calyces.

The major calyces are larger and more funnel-shaped structures that receive urine from the minor calyces. They then transport the urine to the renal pelvis, which ultimately drains into the ureter.

The main function of both the minor and major calyces is to collect and transport urine from the renal pyramids to the ureter for elimination from the body. They act as important anatomical structures that aid in the filtration process of the kidneys.

Issues with the minor and major calyces may include blockages, infections, or abnormalities which may require medical intervention for proper kidney function.
