The errand of the urinary tract is discharging of recycled materials from the body. Correct functioning of this tract provides superintendence of acid and water-salt balance.
During twenty-four hours, this tract passes via itself about 175 liters of blood. The operation of this tract has a precise algorithm: firstly, urea forms in the renal pelvis, than it bit by bit penetrates into the bladder. When this organ accumulates 200-300 ml of the liquid, receptors, which are placed inside its walls, spread alerts to the brain that there is the need to go to the washroom. The fluid build happens during 3-3.5 hours prior to removing it out. For the time of this action the piss is pushed out into the urethra, and later output outwards. After that sphincters are slammed shut, and the piss commences again. A person whose urinary system works correctly can supervise allocation of piss or even delay it. It is critical not to give the urea to build up in the organism. Visit the lavatory as soon as you feel the desire. If you do not adhere to this rule dangerous microorganism will multiply in the organism, it and would cause a contagion.
Human`s excretory tract has a complex anatomy and comprises a few entrails. Concretely:
- Kidneys
- Urethra
- Bladder
- Inner opening of the urethra
- Sphincters
- Nerve terminals
- The vein and the aorta, that leads to the heart
- Suprarenal gland
The size of a kidney in diameter varies from 10 to 12 cm, thickness approximately 4 cm. Their color may range from pale gray to brown, depending on the stage of the blood purification.
Given the age and gender, urogenital system has certain characteristics.
Children`s entrails are undeveloped. It will take several years for the definitive development.
The structure of the urinary tract viscera in both genders is nearly identical; otherness among them is only in the urethra. The female`s bladder has an oval shape (as opposed to a more spherical in men) and is located lower and horizontally. The tension of the uterus often modifies the shape of the bladder, creates a groove on atop of its contour and gives the bladder a saddle shape, in males the prostate may squeeze the bladder, but only if it`s inflamed or swollen. In men, the urethra allocates not only piss but also semen. Male urethral tube is petty and long (20-40 cm, width 8 mm), in women it is wide and short (3-4 cm, and width 1-1.5 cm). Because of that, females are more prone to inflammatory illnesses, since it is simpler for an infection to get inside.
Clinical sign of renal dysfunction is the presence of protein or sugar in the urinalysis.
Emptying, i.e. urine outflow, in healthy women should take place 5-6 times a day, males 4 times daily. At night, during sleep, urinating, as a rule, should not be present.
