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 .
The urinary bladder is formed partly from the endodermal cloaca and partly from the ends of the Wolffian ducts. In other words, the allantois takes no share in its formation. After the separation of the rectum from the dorsal part of the cloaca, the ventral part becomes the primary urogenital sinus . [ 2 ]
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.
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 muscle helps maintain continence of urine along with the internal urethral sphincter which is under control of the autonomic nervous system.The external sphincter muscle prevents urine leakage as the muscle is tonically contracted via somatic fibers that originate in Onuf's nucleus and pass through sacral spinal nerves S2-S4 then the pudendal nerve to synapse on the muscle.

The urethral sphincter is considered an integral part of maintaining urinary continence, and it is important to understand its role in some conditions: Stress urinary incontinence is a common problem related to the function of the urethral sphincter. Weak pelvic floor muscles, intrinsic sphincter damage, or damage to the surrounding nerves and ...
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.
