The internal kidney structures that funnel the urine into the renal pelvis of the ureter are called the calyces.
First of all, urine is created in kidneys, after which it needs to leave the body given that it contains unnecessary fluids as well as other harmful materials. Next step is going into the calyces, after which urine passes into the renal pelvis, and ultimately into the ureter, after which it leaves the body.
