Detailed explanation-1: -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-2: -The renal pelvis drains into the ureter. The renal pyramids are in the medulla.
Detailed explanation-3: -The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.
Detailed explanation-4: -Urine drains from the ducts in the papilla into a renal calyx. Each calyx is lined by transitional epithelium, or urothelium. The calyces merge into the renal pelvis.
