The nephron is the minute or microscopic structural and functional unit of the kidney.It is composed of a renal corpuscle and a renal tubule.The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule.
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
Uriniferous tubules: any of the small tubules that are the excretory units of the vertebrate kidney; Uveoscleral pathway: a tubule that drains excess aqueous humor; Vasa efferentia: convoluted tubules that lead from the rete testis to the vas deferens and form the head of the epididymis [2]
Each uriniferous tubule, along with the vasculature supplying it, is embedded in the interstitium. [ 13 ] Approximately 18–26 different cell types have been described in mammalian kidneys, with a large variation in the range due to a lack of consensus on what counts as a particular cell type, and likely to species differences.

The formation of urine begins within the functional unit of the kidney, the nephrons. Urine then flows through the nephrons, through a system of converging tubules called collecting ducts. These collecting ducts then join together to form the minor calyces, followed by the major calyces that ultimately join the renal pelvis. From here, urine ...

Signals released from the ureteric bud induce the differentiation of the metanephrogenic blastema into the renal tubules. As the renal tubules grow, they come into contact and join with connecting tubules of the collecting duct system, forming a continuous passage for flow from the renal tubule to the collecting duct. Simultaneously, precursors ...
