One of the two tubes which take urine from the kidneys to the urinary bladder.
Either of a pair of thick-walled tubes, about 12 inches (30 centimeters) long, that transport urine from the kidney to the urinary bladder.
One of two small tubes that drain urine from the kidneys to the bladder.
The tube that transports urine from each kidney to the bladder. Each ureter is made of fibrous connective tissue and smooth muscle. Urine flows down the ureters by means of gravity and peristalsis, a pumping action as contractions pass through the delicate muscle layers in the ureters walls. Each ureter enters the bladder through a passage in the bladder wall.
Either of a pair of tubes, 25-30 cm long, that conduct urine from the pelvis of kidneys to the bladder. The walls of the ureters contain thick layers of smooth muscle, which contract to force urine into the bladder, between an outer fibrous coat and an inner mucus layer.
The tube that carries urine from the kidney to the urinary bladder. There are two ureters, one for each kidney, and they originate from the kidney pelvis and track for 25-30 cm (10-12 inches) through the loins and pelvis. They open by a narrow slit into the base of the bladder. The lower end of the ureter pierces the wall of the bladder so obliquely (lying embedded in the wall for about 21 mm) that, although urine runs freely into the bladder, it is prevented from returning up the ureter as the bladder becomes distended.
The conduit responsible for conveying urine from the kidney to the bladder is referred to as the ureter.
One of the pair of tubes responsible for transporting urine from the kidneys to the bladder. Urine travels through the ureters, propelled partially by gravity and primarily through peristalsis, which involves rhythmic contractions of the muscular walls of the ureters.
The length of each ureter is approximately 25–30 cm. The walls of the ureters consist of three layers: an outer layer composed of fibrous tissue, a middle layer of muscular tissue, and an inner layer that is impermeable to water. Blood vessels and nerves provide the ureters with their necessary supply. They connect to the bladder through a passageway within the bladder wall, oriented at an angle to hinder the reflux (backward flow) of urine into the ureters when the bladder muscle contracts.
Certain individuals are born with duplex (double) ureters, occurring on one or both sides of the body, often accompanied by a partially duplex kidney on the affected side. These double ureters might either remain distinct throughout their entire length or merge to create a Y-shaped configuration. While this condition is often asymptomatic, in cases where duplicated ureters enter the bladder separately, vesicoureteric reflux (urine flowing back into the ureter) can occur. Challenges might also arise, like incontinence or infections, if a ureter enters the urethra or vagina instead of the bladder. Surgical intervention can be considered for correction if necessary.
Ureter spasms can manifest when a stone travels down the ureter or becomes lodged within it. This intensely agonizing situation is frequently referred to as renal colic.
Ureteritis, an inflammatory ailment, can develop due to a stone-induced blockage in the ureter or due to the extension of infection from the bladder.
The duct that carries urine from the kidney to the bladder. It measures approximately 16 to 18 inches in length.
