EXSS 276 Final Exam


The movement of substances from the nephron tubule back into the bloodstream is
referred to as:

nephron replacement.
nephron recirculation.
tubular reabsorption.
tubular secretion.

The movement of substances from the bloodstream into the tubular nephron is referred
to as:

tubular reabsorption.
tubular secretion.
nephron replacement.
nephron recirculation.

The process by which plasma minus protein passes from the glomerulus into the tubular
nephron is by:

diffusion.
osmsosis.
filtration.
endocytosis.

Blood entering the kidney arrives at the glomeruli of each nephron through:

cortical veins
peritubular capillaries
afferent arterioles
vasa recta

Arrange the following structures in the correct order:
1. Collecting duct
2. Loop of Henle
3. Distal convoluted tubule
4. Glomerulus

4, 2, 3, 1
4, 3, 1, 2
2, 3, 1, 4
1, 2, 4, 3

, Glomerulus -> Loop of Henle -> Distal Convoluted Tubule -> Collecting Duct

Water will move:

-In the direction of lower osmotic pressure
-In the direction of higher osmotic pressure
-In the direction of a fluid with the same osmotic pressure
-All of the answer choices are correct

ADH acts on the _____ to regulate facultative water reabsorption.

-proximal convoluted tubules
-descending portions of the nephron loop
-thick and thin segments of the ascending nephron loop
-early and late distal convoluted tubules
-late distal convoluted tubules and collecting ducts

Which is the correct order of filtrate flow?

-glomerular capsule, proximal convoluted tubule (PCT), nephron loop, distal convoluted
tubule (DCT), collecting duct
-nephron loop, glomerular capsule, PCT, DCT, collecting duct
-ascending limb of loop, PCT, DCT, collecting duct
-collecting duct, DCT, PCT, collecting duct, glomerular capsule
-PCT, glomerular capsule, DCT, collecting duct, nephron loop

Which structure of the nephron reabsorbs the most substances?

glomerular capsule
nephron loop
ascending limb
collecting duct
proximal convoluted tubule

Increased secretion of hydrogen ions would result in a(n) ______________ of blood
____________?

increase, pressure
decrease, volume
increase, sodium levels
decrease, pH
increase, urea

Choose the organ of the urinary system and corresponding function that are matched
INCORRECTLY.
