Prof Madaya Dr Than Kyaw 1 8 October 2012 Micturition and micturition reflexes Urine transported from renal pelvis to urinary bladder by peristalsis in the ureters Ureters enter the urinary bladder at an oblique angle to form a functional valve . Joe Pistack MS/ED. Urinary System. Urinary System is comprised of:. Two kidneys: form urine from the blood. Two . ureters. : tubes that conduct urine to bladder from kidneys. One urinary bladder: reservoir holding urine temporarily. Control of the GFR. Autoregulation (local level). Hormonal regulation (initiated by kidneys). Autonomic regulation (by sympathetic division of ANS). Glomerular Filtration. Autoregulation of the GFR . Reabsorption Patel University.

Kidney(s). Ureters. Urinary Bladder. Urethra. Functions:. Filter gallons of fluid from bloodstream. Filter plasma 60 times/day. Responsible for removing:. Toxins. Metabolic Wastes. Excess ions. Dr. imrana ehsan. What do the kidneys do?. The glomeruli “non-discriminantly” filter the blood, and the tubules take back what the body needs leaving the rest as waste to be excreted. Some wastes also can be actively added to the tubular fluid.. Part II. . DR .IMRANA EHSAN. Solute and water . reabsorption. . inLoop. of Henley. Tubular fluid .
