- The renal pelvis. Is a pipe with a form reminiscent of a trumpet, because the principle is broad

Also responsible for the homeostasis of the organism (stable conditions in the body: temperature, blood concentrations of oxygen and carbon dioxide, glucose, sodium, potassium, etc.).
The kidneys are important rowatinex organs of the system of maintaining stability in blood concentrations of ions and water. When the body contains any of the following substances in excess, the kidneys are responsible rowatinex for removing it. Also when we are short of a molecule, kidneys saving to avoid losing urine.
The kidneys purify the blood by eliminating the urea and creatinine - which are toxic molecules resulting from the degradation of proteins, bilirubin - which is what remains after hemoglobin-degrading, etc..
- The renal pelvis. Is a pipe with a form reminiscent of a trumpet, because the principle is broad and then narrows. The renal pelvis leaves the kidney retains the medial part called the hilum of the kidney and ureter narrows to form. By drilling the papilla pass urine and the renal pelvis is the collection system.
It is a bag that stores urine until it comes to its evacuation. It is located in the lower abdomen, the pelvic cavity between the rectum and the pubic bone or pubis between the matrix and women ..
The bladder is covered by several layers rowatinex of interwoven smooth muscle, called together detrusor muscle. Around the opening of the urethra, bladder smooth muscle rowatinex forms the internal urethral sphincter.
It is a short tube that goes from the underside of the urinary bladder and communicates with the outside. In the beginning there is the external urethral sphincter and its end is the exit wound, urinary meatus.
The female urethra is very short, about 3.5 cm long and flows together with the anterior wall of the vagina, the opening between the labia minora meatus, ahead of that. The male urethra for 15-20cm and has a ride S common for urinary tract and reproductive rowatinex system. Crossing the prostate and continues inside the penis to the urinary meatus.
Urine is formed in the nephron, rowatinex which is the functional unit of the kidney. The nephron is a conduit of microscopic thickness, which are distinguished corpuscle and renal tubule. Each kidney has about a million nephrons.
From the cabbage capillary leak into the interior of Bowman's capsule 180 liters of water every day, water still is not urine, but only the first step in the formation of this (GFR) . Water passing small molecules. No past or protein or blood cells = GFR.
This part is absorbed from the small molecules filtered and secreted it in others, so that the composition and concentration of the blood back to the general circulation is appropriate. The fluid is excreted as urine.
Also in the tubule rowatinex where urine is concentrated when the body suits to save water. The end walls of the tubule may be permeable to water, water to reabsorb urine, this will be more concentrated and will eliminate less quantity.
- The ADH is a hormone that stimulates the reabsorption of water in the tubules and therefore concentrated urine. People with diabetes insipidus and ADH are not therefore eliminate large volumes of urine diluted. Therefore, it suffers a constant thirst and drinking large amounts of liquid - polydipsia-.
- The Aldosterone is a hormone that stimulates the reabsorption of sodium rowatinex and water and secretion of potassium. The greater absorption of these components will increase rowatinex the plasma volume and therefore blood pressure.
Urine passes through rowatinex the ureters and is deposited in the bladder. When you accumulate a certain amount rowatinex of urine in the bladder, the intravesical pressure increases and this stimulates the nerve receptors in the wall. These impulses sent to:
As in the case of defecation, reflex evacuation centers rowatinex may be detained for thrombosis socially if that is not the right time to evacuate. We get contracted by the external urethral sphincter of voluntary muscles.
If the time is appropriate to evacuate, you need not inhibit the sphincter continues to volunteer and then relaxed and the bladder contracts to push urine. So urination occurs. You may also start urinating but not the bladder is full.
The composition of the urine depends on what is needed to remove the body or save for him.
If the excretory system works normally, urine eliminated a lot of waste products from the body, so examining the quantity and characteristics of urine, obtained interesting data for evaluate the performance of this device.
The examination of the urine excretory function monitoring will be needed when the person
