a. ureters, urinary bladder, urethra b. urinary bladder, ureters, urethra c. urethra, urinary bladder, ureters d. urinary bladder, urethra, ureters
a. ureters, urinary bladder, urethra
Components of a renal corpuscle include
a. a glomerulus and glomerular capsule b. visceral and parietal layers of a renal c. a renal tubule d. all of the above
a. glomerulus and glomerular capsule
Which term describes the tip of a renal pyramid that projects toward the renal sinus?
a. minor calyx b. major calyx c. renal papilla d. renal column
c. renal papilla
Components of a renal corpuscle include
a. a glomerulus and glomerular capsule b. visceral and parietal layers of a renal capsule c. a renal tubule d. all of the above
a. a glomerulus and glomerular capsule
Movement of water and most solutes from tubules to the peritubular capillaries is
a. tubular reabsorption b. tubular secretion c. glomerular filtration d. glomerular secretion
a. tubular reabsorption
During reabsorption water and solutes return to the blood from the tubules.
During which steps of urine formation are substances actually removed from the blood?
(1) filtration (2) reabsorption (3) secretion
a. 1 and 2 b. 2 and 3 c. 1 and 3 d. 1, 2 and 3
c. 1 and 3 Correct
High intensity exercise can cause the GFR to
a. Increase b. Decrease c. Remain unchanged d. Cease
b. Decrease
The volume of fluid filtered by the renal corpuscle is larger than capillaries in other areas of the body due to all the following, EXCEPT
a. Glomerular capillary blood pressure is high b. Glomerular capillaries have a large surface area c. Glomerular capillaries have large fenestrations d. Glomerular capillaries have less plasma proteins
d. Glomerular capillaries have less plasma proteins
Hormones responsible for regulating GFR include
a. Angiotensin II and ANP b. ANP and aldosterone c. Aldosterone and angiotensin II d. Aldosterone, ANP and angiotensin II
a. Angiotensin II and ANP
Angiotensin II and atrial natriuretic peptide. Aldosterone increases blood volume by causing sodium and water retention.
Hydrogen and potassium ions are secreted into the tubular fluid in the
a. renal corpuscle b. proximal convoluted tubule c. nephron loop d. distal convoluted tubule
d. distal convoluted tubule Correct
Reabsorption is the movement of fluid and solutes from the
a. filtrate into the glomerular capillaries b. tubular fluid into the capsular space. c. tubular fluid into the peritubular capillaries. d. blood vessels into the collecting ducts
c. tubular fluid into the peritubular capillaries.
Tubular fluid from the proximal convoluted tubule next travels to the
b. collecting duct c. distal convoluted tubule d. loop of Henle
d. loop of Henle Correct
Juxta glomerular cells secrete
a. angiotensin II b. renin c. angiotensin I d. aldosterone
b. renin Correct
Effects of angiotensin II includes
a. Increases GFR b. Decreases sodium absorption c. vasoconstriction of afferent arterioles d. all of the above.
c. vasoconstriction of afferent arterioles
Which of the following structures assist in producing more concentrated urine?
a. glomerular capsules b. renal tubules and collecting ducts c. minor calyces and major calyces d. ureters and urinary bladder
b. renal tubules and collecting ducts
