Question 1

Match the hormone with the function.
-ADH
A)increases water permeability in the distal convoluted tubule and collecting ducts
B)affects Na+ and Cl- transport in the nephron and collecting duct
C)causes production of Angiotensin II
D)acts as a vasoconstrictor and stimulates aldosterone secretion
E)produced by heart, inhibits ADH production, reduces ability of the kidney to concentrate urine

Accepted Answer

ADH (antidiuretic hormone) increases water permeability in the distal convoluted tubule and collecting ducts, allowing for more water reabsorption and concentration of urine.

Question 2

Match the hormone with its effect on blood pressure.
-ADH
A)↑ BP
B)↓ BP

Accepted Answer

ADH (antidiuretic hormone) causes increased water retention in the kidneys, leading to an increase in blood volume and ultimately an increase in blood pressure.

Question 3

Match the result with the correct part of urine formation.
-plasma minus blood cells and proteins that enter renal tubules
A)filtration
B)tubular reabsorption
C)tubular secretion

Accepted Answer

Filtration is the process of separating plasma from blood cells and proteins that enter the renal tubules.

Question 4

Match the result with the correct part of urine formation. -rids body of excess H⁺ A)filtration B)tubular reabsorption C)tubular secretion

Accepted Answer

Tubular secretion is the process where excess hydrogen ions (H+), potassium ions (K+), and other waste products like drugs are removed from the blood and secreted into the urine for elimination.

Question 5

Match the hormone with the function.

A)increases water permeability in the distal convoluted tubule and collecting ducts
B)affects Na+ and Cl- transport in the nephron and collecting duct
C)causes production of Angiotensin II
D)acts as a vasoconstrictor and stimulates aldosterone secretion
E)produced by heart, inhibits ADH production, reduces ability of the kidney to concentrate urine

Accepted Answer

Atrial natriuretic hormone is produced by the heart and inhibits ADH production, reducing the ability of the kidney to concentrate urine.

Question 6

Match the hormone with the function.
-renin
A)increases water permeability in the distal convoluted tubule and collecting ducts
B)affects Na+ and Cl- transport in the nephron and collecting duct
C)causes production of Angiotensin II
D)acts as a vasoconstrictor and stimulates aldosterone secretion
E)produced by heart, inhibits ADH production, reduces ability of the kidney to concentrate urine

Accepted Answer

Renin is an enzyme that catalyzes the conversion of angiotensinogen to angiotensin I, which is then converted to angiotensin II, a potent vasoconstrictor.

Question 7

Match the hormone with the function.
-aldosterone
A)increases water permeability in the distal convoluted tubule and collecting ducts
B)affects Na+ and Cl- transport in the nephron and collecting duct
C)causes production of Angiotensin II
D)acts as a vasoconstrictor and stimulates aldosterone secretion
E)produced by heart, inhibits ADH production, reduces ability of the kidney to concentrate urine

Accepted Answer

Aldosterone affects Na+ and Cl- transport in the nephron and collecting duct.

Answer: D 
 Aldosterone acts as a vasoconstrictor and stimulates aldosterone secretion.

Question 8

Match the structure with the appropriate description.
-Bowman's capsule
A)supplies blood to the glomerulus
B)enlarged proximal end of nephron
C)gaps between the podocyte processes
D)plexus of capillaries around tubules
E)arteries that arch over bases of the pyramids

Accepted Answer

Bowman's capsule is the enlarged proximal end of the nephron that encases the glomerulus.

Question 9

Match the hormone with its effect on blood pressure.
-angiotensin II
A)↑ BP
B)↓ BP

Accepted Answer

Angiotensin II causes vasoconstriction and increases blood pressure.

Question 10

Match the hormone with its effect on blood pressure.
-renin
A)↑ BP
B)↓ BP

Accepted Answer

Renin is an enzyme that stimulates the production of angiotensin II, which is a potent vasoconstrictor. This vasoconstriction leads to an increase in blood pressure.

Question 11

Match the result with the correct part of urine formation.
-the fate of 99% of the filtrate
A)filtration
B)tubular reabsorption
C)tubular secretion

Accepted Answer

Tubular reabsorption is responsible for reabsorbing 99% of the filtrate back into the bloodstream, leaving only waste products to be eliminated in urine.

Question 12

Match the term with the appropriate definition.
-reabsorption
A)amount of blood flowing through kidneys per minute
B)amount of plasma filtered through filtration membrane
C)movement of plasma across filtration membrane
D)movement of substances from filtrate back into blood
E)non-reabsorbed filtrate

Accepted Answer

Reabsorption is the movement of substances from the filtrate back into the blood.

Question 13

Match the term with the appropriate definition.
-filtration
A)amount of blood flowing through kidneys per minute
B)amount of plasma filtered through filtration membrane
C)movement of plasma across filtration membrane
D)movement of substances from filtrate back into blood
E)non-reabsorbed filtrate

Accepted Answer

Filtration refers to the movement of plasma across the filtration membrane in the kidneys.

Question 14

Match the result with the correct part of urine formation.
-an increase in aldosterone secretion promotes this
A)filtration
B)tubular reabsorption
C)tubular secretion

Accepted Answer

Aldosterone promotes sodium and water reabsorption in the distal tubules and collecting ducts, leading to an increase in tubular reabsorption.

Question 15

Match the term with the appropriate definition.
-renal blood flow
A)amount of blood flowing through kidneys per minute
B)amount of plasma filtered through filtration membrane
C)movement of plasma across filtration membrane
D)movement of substances from filtrate back into blood

Accepted Answer

Renal blood flow refers to the amount of blood that flows through the kidneys per minute.

Question 16

Match the term with the appropriate definition.
-filtration fraction
A)amount of blood flowing through kidneys per minute
B)amount of plasma filtered through filtration membrane
C)movement of plasma across filtration membrane
D)movement of substances from filtrate back into blood
E)non-reabsorbed filtrate

Accepted Answer

Filtration fraction refers to the amount of plasma that is filtered through the filtration membrane in the kidneys.

Question 17

Match the result with the correct part of urine formation. -rids body of excess K⁺ A)filtration B)tubular reabsorption C)tubular secretion

Accepted Answer

Tubular secretion is the process by which the kidneys remove excess substances, such as potassium ions, from the blood and add them to the urine.
