GENERAL HISTOLOGY

Detailed explanation-1: -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. Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla).

Detailed explanation-2: -In turn, the major calyces join to form the funnel-shaped renal pelvis. * The renal pelvis collects urine from the calyces and transports it to the ureter.

Detailed explanation-3: -There are 7-12 minor calyces in each kidney. There are 2-4 major calyces in each kidney. Several minor calyces empty into one larger major calyx. These structures are important for removing urine from the kidneys.
