Exam 31: A: Urinary System

The three openings on the bladder floor make up the trigone.

The fibrous adventitia covers only the superior surface of the bladder; the rest is covered by the parietal peritoneum.

Glomerular osmotic pressure and capsular osmotic pressure are equally important in determining the GFR.

There are three openings in the floor of the urinary bladder-two from the ureters and one into the urethra.

The blood vessel that surrounds the loop of Henle is called the vasa recta.

About 10% of the blood pumped by the heart per minute goes to the kidneys.

The renal fasciae anchor the kidney to surrounding structures.

A hormone that affects reabsorption in the kidney is made in the wall of the heart.

The connective tissue that anchors the kidney to the surrounding structures is called the renal cortex.

Kidney disease can be diagnosed by taking a tissue sample by means of a needle biopsy.

Osmosis in the kidney relies on the availability of and proper function of aquaporins.

Gravity moves urine from the kidney to the bladder through the ureter.

The kidneys are surrounded by fat and are enclosed by the parietal peritoneum.

Capsular osmotic pressure can be assumed to be zero.

The principle organs of the urinary system are the kidneys.

Nitrogenous wastes such as urea,uric acid,and ammonia are lost in the urine,and of these,uric acid is the most abundant.

Micturition is the process of voiding urine.

As the amount of sodium increases in the blood around the distal convoluted tubule,the amount of potassium or hydrogen ions in the filtrate increases.

The renal pyramids are in the medulla of the kidney.

The transitional epithelium that lines the bladder wall is one factor that allows the bladder to distend.
