• For the regions of the collecting ducts located deep in the medulla, the generation
of urine with a high osmotic strength requires a high concentration of ______ in
the interstitial space. -✓✓ urea
• The three major functions of the renal system are:
Select all that apply. -✓✓ Remove nitrogenous waste, Regulate blood pH,
Regulate salt and water balance
• Which of the following is the correct order of blood flow through the renal
corpuscle? -✓✓ Afferent arteriole, glomerulus, efferent arteriole
• The epithelial cells of Bowman's capsule are called _________________ -✓✓
podocytes
• The glomerulus is a tuft of capillaries in the renal compartment and Bowman's
capsule is part of the blood vascular compartment. (true or false) -✓✓ false
The glomerulus is a tuft of capillaries in the blood vascular compartment.
,Bowman's capsule is part of the renal compartment.
• ***This is an example of a test question***
Water moves from Bowman's capsule into the glomerular capillaries because the: -
✓✓ osmotic pressure generated by plasma proteins is higher in the capillaries than
in Bowman's capsule
• The peritubular capillary is an extension of the efferent arteriole which wraps
around the ______________. -✓✓ Proximal convoluted tubule
• Urine has a ____________ ion concentration in the cortex of the kidney when it
is in the ____________________________. -✓✓ low, proximal convoluted tubule
• In the proximal convoluted tubule water and most ions follow a
___________________ route, meaning they leave the lumen by passing between
the tight junctions of the epithelial cells. -✓✓ Paracellular
• When Na+, glucose and amino acids move in across the epithelial cells of the
proximal convoluted tubule, they are reabsorbed by the ________________. -✓✓
Peritubular capillary
• ***This is an example of a test question***
GLUT 2 is a glucose transporter that permits glucose transport by facilitated
diffusion. You would expect to
, find this protein in: -✓✓ basilar membranes of epithelial cells in the proximal
convoluted tubule
• The concentration increases as the filtrate moves from the cortex to the medulla.
(true or false) -✓✓ true
• Macula densa cells in the DCT release ________________, which bind to
GPCRs on the afferent arteriole in response to a high glomerular filtration rate. -
✓✓ Adenosine
• The thick segment of the ascending limb contains passive ion channels and the
thin ascending limb contains ion channels requiring ATP. (true or false) -✓✓ false
The thin segment contains passive ion channels and the thick ascending limb
contains ion channels that require energy
• The descending limb only contains _______________ and lacks
________________ -✓✓ aquaporins, ion channels
• ***This is an example of a test question***
Smooth muscle relaxation in the ____ would increase Glomerular Filtration Rate
(GFR). -✓✓ Afferent arteriole
