Answer:
How is it diagnosed
Tests to prove the existence of a urinary stone are simple abdominal radiography and renovesical ultrasound. Sometimes it is necessary to complete the study with tests such as abdominal CT or intravenous urography, which allows a better visualization of the anatomy and the exact size and location of the stones within the urinary tract. For the study and metabolic control of lithiasic disease it is necessary to perform a blood test and a 24-hour urine test. The composition of the calculation is determined with microscope observation and spectrometry.
Which is the treatment
Extracorporeal shock wave lithotripsy (LEOC) is the treatment of choice for most lithiasis in any of its locations. It is about breaking the stone without surgically intervening the patient and getting him to eject the fragments. When the LEOC is ineffective or not indicated, different types of surgery can be performed to solve the problem. If the lithiasis is in the ureter, endoscopic surgery such as ureteroscopy can be performed. When the calculus is in the kidney or its size is greater than 2-3 cm, for example in coral stones, a percutaneous nephrolithotomy (NLP) is performed, through which the inside of the kidney is accessed through the area lumbar. Laparoscopy is an option for special cases of stones in the ureter or renal pelvis. Open surgery is currently applied in very few cases. Bladder stones (bladder stones) are treated with endoscopic techniques but if the stone is bulky, a small incision can be made in the lower abdomen for removal.
For the medical treatment of lithiasis there are very few effective medications. Potassium citrate is useful to prevent the formation of oxalate stones and to dissolve those of uric acid. Thiazide-type diuretics reduce the expulsion of calcium in the urine (hypercalciuria).
Waste/toxins would not be able to leave the body. The kidneys filter out the waste and eliminate it through the urinary tract.
A. Flexibility.
Flexing loves to move those muscles! :D
The correct answer is: Baroreceptors in the arteries send a signal to the brain that the blood pressure is low. The brain sends a chemical signal to the heart to increase its rate of pumping. This continues until the baroreceptors sense a normal blood pressure.
A negative feedback loop occurs in the body when something in the body has decreased in function, which could mean high or low, for example blood sugar, body temperature or in this in this case blood pressure. It then creates a feedback loop to tell that part of the body to regulate itself and return the body to a state of homeostasis (which is your optimal internal state). In a negative feedback loop the response of the regulating mechanism is opposite to the output of the event. So if blood pressure is low the negative feedback loop will tell the body to increase the pressure.
A positive feedback will result in more of a product: more prolactin, more contractions, or more clotting platelets.
