The structure of the ureter is as follows: external and internal muscle tissue, blood vessels and epithelium, covered with mucous membrane. With the help of blood vessels, the organ itself is fed, as well as the layer of the epithelium. The ureter is located in three departments: abdominal, pelvic, distal. It performs an important function.
Definition: what is the ureter in biology
In the human body, the ureters play an important role and are an integral paired organ of the reproductive system. Their main function is to connect the kidneys and bladder. Simply put, the ureter is a kind of tube, the diameter of which is 6-8 millimeters, and the length is 25-30 centimeters.
To understand what the ureters are, just imagine a medical catheter designed to collect urine. This body looks approximately like that, in simple terms.
There are three natural contractions in the ureter - this is the exit from the pelvis, at the beginning of the pelvis and in the cystic wall. Urine moves through the ureter due to contractions of the cystoids. The work of organs is controlled by the autonomic nervous system. Calcium has a great influence on the functioning of the ureters. The strength of contraction depends on how much it is contained in muscles and tissues.
Where are the ureters
Representatives of the male and female sexes are located in different ways. In women, they round the uterus and are located behind the ovaries, in the space between the bladder and the vagina. In men, the ureter passes on top of the seminal streams. The most distant site from the kidneys is distal. It is located in the wall of the bubble, and its length is one and a half to two centimeters.
The ureters in males are longer than females by about two to three millimeters. But the right ureter in all people is slightly smaller than the left. This is because the right kidney is more developed and active.
Congenital diseases of the paired organ
Recently, problems with the genitourinary sphere are very common. The ureters are no exception. Diseases are congenital and acquired. The first include pathologies in which the shape, structure and location of the ureters are disturbed. Accordingly, they arise during pregnancy. The presence or absence of signs of pathology depends on its severity.
Most often, symptoms such as lower back pain or any violation of urination occur. After all, what are the ureters? These are tubes, the movement of which can be difficult, because of which there is pain or problems with the withdrawal of urine. For examination, general tests, ultrasound of the genitourinary system, excretory urography, cystogram, and MRI can be prescribed. Only congenital pathologies are treated with the surgical method.
Acquired diseases
These diseases include stones and, as a result, inflammatory diseases of the ureters. They arise due to injuries resulting from the movement of salts. If the pathological process is not treated, then it can easily switch to other organs.
If acute inflammation occurs, then the main symptom is renal colic, severe, unbearable pain in the lower back and abdomen. It occurs due to the movement of stones. Also, with inflammation of the ureters, the color and smell of urine change, the body temperature rises and constant fatigue is felt.
As a prophylaxis of diseases of the genitourinary organs, you can cook and regularly drink cranberry and cranberry fruit drinks. It is also useful to take infusions from brewed berry leaves.
We found out what the ureters are, how they are arranged and what functions they perform. It remains to say that the most important thing in the prevention of diseases of the urinary system is not to chill, not to eat a lot of salty and spicy foods and, of course, not to neglect unpleasant symptoms and not to self-medicate, but to go to the doctor and undergo the necessary treatment.
