Ureter

The ureter (Ureter) is a paired cylindrical tube 25-30 cm long, through which urine flows from the renal pelvis to the bladder. Contraction of the smooth muscles of the ureteral wall, which are located between the outer adventitia and inner mucosa, promotes the movement of urine into the bladder. Ureteral (ureteral, ureteric) - related to the ureter.



The ureters are paired cylindrical tubes 25 to 30 centimeters long, through which urine from the renal pelvis enters the bladder, where it is accumulated and excreted. The ureters are part of the body's urinary system and play an important role in the process of urination.

The ureters consist of three layers: the outer adventitia, the middle muscularis and the inner mucosa. The smooth muscles located between these layers contract, which helps move urine from the kidneys to the bladder.

An important factor influencing the function of the ureters is their anatomical structure. They have a special shape that ensures the unhindered passage of urine. In addition, the ureters have a number of physiological features, such as the presence of valves that prevent the backflow of urine.

Impaired ureteral function can lead to various diseases. For example, stones in the ureters can cause pain and difficulty urinating, and can lead to urinary tract infections. Also, abnormalities in the development of the ureters can lead to disruption of the outflow of urine and the development of hydronephrosis, a condition in which the bladder is full of urine.

To prevent ureteral diseases, you need to monitor your health and undergo regular medical examinations. If any violations are detected, you must consult a doctor for treatment and further observation.



Ureters The ureters, a paired tubular organ of the excretory system of vertebrates, connects the kidney to the bladder and removes urine from the kidney to the bladder. The length of the human ureter is about 30 centimeters. Humans have two ureters - left and right, while other mammals have one. In addition, as a consequence of embryonic development, part or all of the ureters of unpaired representatives of reptiles, some birds, fish and reptiles fuse with their posterior ends into an unpaired ureter. A pair of ureters is located in the pelvic cavity, on its back wall under the upper sections of the bladders. Their outer end ends blindly on the side wall of the spine at the exit point of the V pair of lumbar vertebrae. In men, the vas deferens departs from the ureter above the level of the vertebra, and in women, the fallopian tube. At its passage through the dorsal wall of the pelvis, the ureter lies between the rectal ampulla and the pelvic nerves. The inner lining of the ureters is rich in spiral
