Renal papilla. The renal papilla is the tip of each renal pyramid where urine is collected before being expelled into the minor calyx.
The conical mass of tissue within the renal medulla is called the renal pyramid. This structure is involved in the production of urine and contains the nephrons, which are the functional units of the kidney responsible for filtering blood and producing urine.
Major calicesThe renal pelvis is also known as the pyelum The renal pelvis acts as a funnel for urine from the kidney to the urethra .
This structure is likely describing the renal papilla, which projects into the minor calyx in the kidney. The renal papilla is the tip of the renal pyramid containing the openings of the collecting ducts for urine drainage into the renal calyces and eventually the renal pelvis.
The ureter expands within the kidney to collect urine filtered by the neprhons. The renal pyramid is not made up of the ureter.
One million functional units
ureter
From the renal papilla, urine flows into the renal calyx, then into the renal pelvis. From there, it travels through the ureter to the bladder for storage until it is expelled from the body through the urethra.
Urine goes to the collecting duct then to the Renal Pelvis. Each kidney has one Ureter that carries Urine to the bladder. The urine from the kidneys flows down the ureters into the bladder and is then passed out of the body through the urethra.
Ureter
The calyx or calyces is the part of the kidney where the urine flows through.
The renal pelvis is the structure in the kidney that empties into the ureter. It collects urine from the calyces and funnels it into the ureter for transport to the bladder.
