Exam 15: The Urinary System

Extracellular fluid is found everywhere in the body EXCEPT ________.

The bicarbonate buffer system prevents changes in blood pH through the action of carbonic acid and its salt, sodium bicarbonate.

Urine is transported from the urinary bladder to the outside of the body by the ________.

The need to urinate frequently at night, which plagues over 50% of the elderly, is called ________.

Using Figure 15.2, identify the following: -The glomerulus is indicated by ________.

Trace the pathway of a red blood cell through the kidney from the renal artery to the renal vein.

Which one of the following is NOT a substance typically reabsorbed by the tubules under normal healthy conditions?

Filtrate formed during glomerular filtration is captured by the ________.

The capillary bed surrounding the renal tubule is the ________.

The tube connecting each kidney to the urinary bladder is the ________.

Identify the urinary structure with its associated description: A) renal vein B) renal medulla C) calyces D) renal pelvis E) renal (medullary) pyramids F) renal columns G) renal cortex -Cup-shaped extensions of the pelvis that enclose the tips of the renal (medullary) pyramids

Using Figure 15.1, identify the following: -The renal pelvis is indicated by ________.

Antidiuretic hormone (ADH) causes increased water loss through the urine.

When blood pH becomes too acidic, the tubule cells of the kidneys excrete bicarbonate ions and retain hydrogen ions.

Most reabsorption occurs in the proximal convoluted tubule of the nephron.

Who has the highest percentage of water in the body?

Identify the urinary structure with its associated description: A) renal vein B) renal medulla C) calyces D) renal pelvis E) renal (medullary) pyramids F) renal columns G) renal cortex -Darker, reddish-brown internal area of the kidney

Antidiuretic hormone prevents excessive water loss by promoting water reabsorption in the ________.
