The typical adult human bladder will hold between 300 and 500 ml (10 and 17 fl oz) before the urge to empty occurs, but can hold considerably more. [3] [4] The Latin phrase for "urinary bladder" is vesica urinaria, and the term vesical or prefix vesico-appear in connection with associated structures such as vesical veins.
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites , and regulate blood pH .
In humans, soluble wastes are excreted primarily by the urinary system and, to a lesser extent in terms of urea, removed by perspiration. [4] In placental mammals, the urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The system produces urine by a process of filtration, reabsorption, and tubular secretion. The ...
The urethra (pl.: urethras or urethrae) is the tube that connects the urinary bladder to the urinary meatus, [1] [2] through which placental mammals urinate and ejaculate. [3] In non-mammalian vertebrates, the urethra also transports semen but is separate from the urinary tract.
The genitourinary system, or urogenital system, are the sex organs of the reproductive system and the organs of the urinary system. [1] These are grouped together because of their proximity to each other, their common embryological origin and the use of common pathways. Because of this, the systems are sometimes imaged together.

Like the bony pelvis, the renal pelvis (/ ˈ r iː n əl ˈ p ɛ l v ɪ s /) gets its English name via Neo-Latin from the older Latin word pelvis, "basin", as in "wash basin". [4] In both cases the name reflects the shape of the structure, and in the case of the renal pelvis, it also reflects the function.

The urachus forms from the distal end of the allantois in the embryo, and develops into a closed cord between the base of the bladder, and the navel. [1] It drains the bladder of the fetus that joins and runs within the umbilical cord. [2]
