The following structures are located in, and make up, the kidney cortex, EXCEPT

Renal corpuscles

Proximal convoluted tubules

Transitional epithelium

Distal convoluted tubules

Each of the following statements concerning the nephrons is true, EXCEPT:

Empty into the minor calyx.

Are functional units of the kidney

Have the renal capsules

Include the proximal and distal convoluted tubules

Each of the following statements concerning the renal corpuscles is true, EXCEPT

Include the double-layered renal capsule

The capsular parietal layer consists of flat cells and surrounds the capsular space

The glomerulus contains continuous- type capillaries

The capsular visceral layer consists of podocytes and surrounds the capillary glomerulus

Each of the following statements concerning the renal filtration barrier is true, EXCEPT

Includes the endothelium of glomerular capillaries

Includes the capsular parietal layer

The glomerular basement membrane is the principal barrier component

The lamina densa of the glomerular basement membrane contains collagen network and acts as a physical filter.

Each of the following statements concerning the renal proximal convoluted tubules is true, EXCEPT

Are more tortuous and longer than the distal convoluted tubules

Possess cuboidal cells specialized for absorption and fluid transport

Lack the brush border and basal striations

Reabsorb 80% of primary filtrate

Each of the following statements concerning the renal distal convoluted tubules is true, EXCEPT

Have cuboidal cells with basal striation;

Their epithelial cells possess the brush border

Reabsorb Na+ under aldosterone control

Reabsorb water under ADH regulation

Each of the following statements concerning the renal collecting tubules is true, EXCEPT

Their cells possess the brush border

Are lined with the cuboidal or low columnar epithelium

Their epithelium includes dark and light cells

Water permeability of their epithelium is regulated by ADH

Each of the following statements concerning the renal macula densa is true, EXCEPT:

Is formed in the distal convoluted tubule at the site of tubule contact with the vascular pole of its parent renal corpuscle

Its cells produce renin.

Is formed in the distal convoluted tubule at the site of tubule contact with the vascular pole of its parent renal corpuscle

Its cells control NaCl concentration in the urine and regulate renin release

Each of the following statements concerning the renal juxtaglomerular cells is true, EXCEPT

Are located in afferent and sometimes in efferent arterioles

Are chemoreceptors and control the blood concentration of NaCl

Synthesize, store, and release renin

Are modified smooth muscle cells

Each of the following statements concerning the transitional epithelium is true, EXCEPT

Lines the mucosa of all excretory passages;

Its surface cells are dome-shaped and bulge into the lumen

Is highly permeable for salts and water

Consists of 5 or 6 layers in unstretched condition

Each of the following statements concerning the juxtamedullary nephrons is true, EXCEPT:

Are the principal nephrons producing the urine

diameters of their afferent and efferent arterioles are equal

Their corpuscles are in proximity to the base of medullary pyramids

Serve for the blood passage during exercise.
