Papillary ducts are narrow tubes in the kidney that merge to form the renal papilla. They empty urine into the renal calyces within the renal sinus.
Renal tubules in the kidney filter waste products, excess ions, and water from the blood to form urine. This process helps in regulating the body's fluid balance and eliminating toxins from the body.
The distal convoluted tubules flow directly into collecting ducts within the kidney, where final modifications to the urine occur before it is delivered to the renal pelvis.
Well when you are doing scientific experiments with test tubes you may put different substances or whatever you're using in different tubes therefore to separate them and study them individually... Does that help you at all?
Renal columns are bands of granular tissue that separate adjacent renal pyramids. They contain vessels and urinary tubes that run to the cortex.

Papillary ducts are narrow tubes in the kidney that merge to form the renal papilla. They empty urine into the renal calyces within the renal sinus.
The renal pelvis is not divided into small tubes. It is a funnel-shaped structure in the kidney that collects urine from the calyces and transports it to the ureter for excretion. The calyces are the structures that are divided into smaller tubes within the kidney.
The renal or urinary system, comprising the kidneys, bladder and connecting tubes, is located in the back of the abdomen (kidneys) and inside the pelvis near the groin (bladder, urethra). The bladder is connected to the kidneys via a pair of tubes called ureters.
Honeycomb cells, Buckminster fullerene tubes.
The outer, reddish region, next to the capsule, is the renal cortex. This surrounds a darker reddish-brown region called the renal medulla. The renal medulla consists of a series of renal pyramids, which appear striated because they contain straight tubular structures and blood vessels. The wide bases of the pyramids are adjacent to the cortex and the pointed ends, called renal papillae, are directed toward the center of the kidney. Portions of the renal cortex extend into the spaces between adjacent pyramids to form renal columns. The cortex and medulla make up the parenchyma, or functional tissue, of the kidney. The central region of the kidney contains the renal pelvis, which is located in the renal sinus and is continuous with the ureter. The renal pelvis is a large cavity that collects the urine as it is produced. The periphery of the renal pelvis is interrupted by cuplike projections called calyces. 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 into the ureter.Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla). The nephrons make up the bulk of the kidney tissue and join up with larger collecting tubes that eventually form the main urine-carrying duct - the ureter Each kidney has an indentation, called the hilum, on the medial side. The hilum leads to a large cavity, called the renal sinus, within the kidney. The ureter and renal vein leave the kidney, and the renal artery enters the kidney at the hilum.Malphigian body can be further divided into glomerulus and bowman's capsule,whereas renal tubules can be divided into proximal convoluted tubule, loop of henle, distal convoluted tubule and collecting tubule.

The tubes inside the kidneys are called renal tubules. These tubules play a key role in filtering blood and reabsorbing essential substances to maintain the body's balance of fluids and electrolytes.
