Chapter 25 - Urinary Anatomy Quiz Flashcards

The glomerulus is a capillary network connected to the afferent and efferent arterioles.

1) True

2) False

The glomerular capillaries:

1) return material to the blood

3) connective tissue

4) detrusor muscle

The role of the urinary bladder is to:

3) Major calyx

4) Medulla

Major calyces are large branches of:

1) a renal column

2) the pelvis

3) the renal sinus

4) interlobular artery

Which of the following describes the renal sinus?

1) A sinus in the renal bone

2) A space on the lateral aspect of the kidney

3) arcuate arteries

4) cortical radiate arteries (interlobular arteries)

5) arcuate veins

The macula densa cells respond primarily to:

1) levels of aldosterone in the blood

2) levels of ADH in the blood

3) changes to hydrostatic pressure in the DCT

4) changes in solute content of filtrate

The functional unit of the kidney is the glomerulus.

1) True

2) False

Renin is present in:

1) the smooth muscle cells of the renal vein

2) the smooth muscle cells of the afferent arteriole

3)the smooth muscle cells of the DCT

4) the columnar cells of the DCT

5) columnar cells of the efferent arteriole

2) have large cuboidal cells

3) have a smaller lumen

4) all of the above

When one passes urine which of the following will happen?

1) contraction of the detrusor and the urinary sphincters

2) contraction of the detrusor and relaxation of the urinary sphincters

3) relaxation of the detrusor and the urinary sphincters

4) relaxation of the detrusor and contraction of the urinary sphincters

Transitional epithelium is ideal as the lining epithelium for the bladder and ureter, because it:

1) is secretory

2) allows filtration

3) stretches/expands

4) has a layer of keratin which is water proof

All of the following statements are true, EXCEPT:

1) The muscle of the bladder is called the detrusor muscle

2) The lining of the bladder is transitional epithelium

3) The area of the trigone show two urethral orifices and one ureteral orifice

4) The urinary bladder receives urine from 2 ureters

The filtration membrane is formed by the parietal layer of the Bowman's capsule, fused basement membranes, and capillary endothelium.

1) True

2) False

Which of the following structures would not be found in the medulla of the kidney?

1) glomerulus

2) descending limb of loop of Henle

3) ascending limb of loop of Henle

4) Collecting duct

Place the structures below in the proper sequence as the filtrate (or urine) would pass through them:
1. Loop of the nephron (loop of Henle)
2. Distal convoluted tubule
3. Proximal convoluted tubule
4. Glomerular (Bowman's) capsule
5. Collecting tubules and duct

1) 3, 2, 1, 4, and 5

2) 4, 3, 2, 1, and 5

3) 3, 4, 1, 2, and 5

4) 2, 3, 1, 4, and 5

5) 4, 3, 1, 2, and 5

The correct sequence for urine flow would be:
1. ureter
2. nephron
3. renal pelvis
4. urethra
5. bladder

1) 2, 1, 3, 4, 5

2) 2, 3, 1, 5, 4

3) 3, 4, 5, 2, 1

4) 1, 2, 3, 5, 4

5) 3, 2, 5, 1, 4

What does the glomerulus and the renal tubule form?

1) juxtaglomerular apparatus

2) nephron

3) Henle's loop

4) none of the above

The Bowman's capsule consists of:

1) Parietal and visceral layers

The hilum of the kidney is present on it's convex lateral surface.

1) True

2) False

A person with kidney damage would be likely to suffer from?

1) Anemia

2) Bleeding disorders

3) Transfusion reactions

4) Decrease in blood supply to all organs
