The lungwort (Pulmonaria) is a genus of herbaceous plants of the family Boraginacea. They bear terminal cymes of bluish flowers, with tubular five- cleft calyces and funnel-shaped corollas. The name is derived from the previous use of Pulmonaria officinalis as a treatment for lung disease.
 Research Lungwort
The calyces are the recesses in the internal medulla of the kidney which enclose the renal pyramids. They are used to subdivide the sections of the kidney anatomically, with distinction being made between major calyces and minor calyces.
Research Calyces
The collecting tubules of the kidney are responsible for collecting the urine from the distal convoluted tubule of the nephron and passing it to the calyces, and from there into the renal pelvis reservoir. The collecting tubules are relatively straight, distinguishing them from the proximal and distal convoluted tubules.
Research Collecting Tubule
The loop of Henle is a U-turn in the tubule responsible for carrying urine out of the nephron and into the calyces. It is bordered by the proximal and distal segments of the convoluted tubule and features both the ascending and descending limb flanking the U-turn.
