What is the Main Function of the Ureter

The tube connecting the urine sac and kidney is called the ureter. Function of the Ureter descriptio is given here Reed article.

Ureter is a thin tube that combines the kidney and a bladder through which the urine gets out of the bladder in the bladder. The structure and function of the urethra provide general functioning of the urinary system. 

Each kidney has its own urate, which emerges from the kidney pelvis and enters the bladder. The length of each ureter is approximately 30 cm, diameter varies from 4 to 7 mm. Urine size is important in urolithiasis. Larger stones than 4 mm can not get out of the urine flow free of bladder and lead to the development of kidney color.

Function of Ureter: stomach and pelvic structure

The kidney goes from the pelvis to the urate direction in the lower and middle and small pelvis, where it enters the bladder, it sprouts its wall in a slanting direction. In each ureter, stomach and pelvic parts are distinguished. The ventral part of the urate is located in front of the large blanket muscles. Prior to the right urate, the descending part of the Duodenum is the basis of the vessels and the small intestine's mesentary. On the left is the basis of a duodenum-genus turning, a vascular bundle and the mesentary of the signomedic colon.

Urater

There are abdominal fibromycachaler tubes which spread from urine to urinary bladder. In smooth muscles the contraction may be like an involuntary wave, and urine can move the bladder urine. This series of organized muscle contractions is known as peristalsis. In adults, about 25 to 30 centimeters of urine is in diameter and about 3 to 4 mm in diameter. The upper part of the urine is suitable in the tissue while the lower half is in the lateral pelvic wall. In males, ureters lie in the white fold and the tract is crossed by mediocrity by deferens. In women, ureters lie in uterosacral bond and are transmitted anterior by the uterine artery. Ureter is embedded in the wall on the back of the urinary bladder for approximately 2 cm. The ureter's lumen is narrow and muscles of the ureter and urinary bladder are continuous.

What is the difference between ureter and urethra?

• Eurethra is the last part of urinary system, while urine is located in the middle of urine system.

• An adult person has two doctors and one urethra

• Eurent urine present urine up to urinary bladder, while the urethra urine passes through the urine from the bladder to the outer.

• The urethra is considered as a part of both the reproduction and urinary system in men, while the urine is considered as a part of urine system.

• Usually urethra is higher than the urethra, but the urethra has a larger diameter than the ureters

• Unlike muscles in the urethra, contractions can occur in the smooth muscles of the ureters using peristalis

The urinary system includes the following physical organs:

• Kidney (renal)
• Urure (Urine) - The main function of the urater is to carry urine through the tube to the urinary bladder.
• urinary bladder
• Uretera (urethra) - A small tube through the urethra which collects urine from the bladder and exits it from the body.

Ureter - Structure and function of urine system

The urate is a thin tube that connects the kidney and the vesicles, through which the urine gets out of the bladder in the bladder. The structure and function of the urethra ensures the normal functioning of the urinary system. Each kidney has its own urate, which leaves the kidneys pelvic and enters the bladder. The length of each ureter is about 30 cm, diameter is from 4 to 7 mm. The size of the urate in urolithiasis is very important. Larger stones than 4 mm can not flow freely with urine in the bladder and can lead to the development of kidney color.

Ureter: stomach and pelvic structure

From the renal pelvis, the urate goes in the direction of the lower and middle pelvis, where it enters the bladder, it sprouts its wall in a slanting direction. Separate the stomach and pelvic part in each urate. The stomach part of the urate is located in front of the large blanket muscles. In front of the right urater is the basis of the Duendenum, the blood vessels and the small intestine mensary. In front of the left is the basis of the duodenal-jejunal flux, the vascular bundle and the mesentary of the syngodymic colon.

In the pelvic part, the urine is moving forward, the ilial artery and veins. In this section the diameter of the ureter is narrowed. In men, it passes in front of the sperm canal and falls under the upper pole of the original vesicle in the bladder. In the pelvic part, the urine in women is surrounded by other organs: Urine passes through the ovaries and uterus uterus, the urinary bladder enters the side of the vagina.

A special part of the urine is located inside the bladder wall.

Ureter: wall structure

The wall of the urate, as well as the kidneys, is accompanied by three membranes: the outer one - the connective tissue, which is covered with the mucous glands and intermediates, through the transitional epithelium, in which the muscles have two layers - the longitudinal And Circular The urethra muscle is not attached to the bladder muscle layer and prevents flow of urine from the urinary bladder.

In its place of urinary entry into the urinary bladder, its wall is a layer of longitudinal muscles, which is closely linked to the layer of urinary bladder muscles. This layer prevents active urine withdrawal in urine. The presence of this layer limits the spread of infection from bladder to urine and then to the kidneys.

Ureter: Lumen Structure

There are many contractions in the lumen of the urate:

• - The first promiscuity is in the area of ​​pelvic infection in the urate;
• - The second is located on the boundary between the stomach and the pelvic part;
• - The third contraction can occur in any part of the pelvic part;
• - The fourth narrow is located near the wall of the bladder.

The presence of natural contraction of urate is great clinical value. In these areas, the stones that emerge from the kidney pelvis and the urine running in the direction of the bladder are trapped.

During the urethra, in addition to creative contraction, corruption is physiologic, which are visible during disappearance and disappear during peristalysis.

Ureter: The structure of blood supply and conservation

The blood from the upper part of the urate receives blood branches from the stomach and testicular or ovarian artery vessels. The middle part is supplied with blood from the uterine branches from the stomach aorta and Iliac artery. Lower - Urine and Middle Rectal Artery The blood outflow occurs in internal iliac and blanket veins.

The protection of the urate is done by following several autonomic nerve plucks. The branches of vaginal nerve and pelvic gut veins provide parasite protection.
