URINARY QUIZ

Question 1

The papillae of the renal pyramids are located close to the renal _____ area.

Answer 1

Pelvis

Question 2

The area where the renal artery enters the kidney and the renal vein and ureter exits the kidney is called the ______.

Answer 2

Renal hilum

Question 3

Which of the following is the correct sequence of blood flow through the kidneys on its route to the glomeruli of the nephrons?

1. renal artery  segmental artery  interlobar artery  interlobular (cortical radiate) artery  arcuate artery  afferent arteriole
2. renal artery  segmental artery  interlobar artery  arcuate artery  (cortical radiate) artery  afferent arteriole
3. renal artery  segmental artery  interlobular (cortical radiate) artery  arcuate artery  interlobar artery  afferent arteriole
4. renal artery  segmental artery  arcuate artery  interlobar artery  interlobular artery  afferent arteriole

Answer 3

2. renal artery  segmental artery  interlobar artery  arcuate artery  (cortical radiate) artery  afferent arteriole

Question 4

What is the correct sequence regarding the flow of waste products through the nephrons of the kidneys?

Answer 4

glomerular capsule  proximal convoluted tubule  loop of Henle  distal convoluted tubule  collecting duct

Question 5

One of the many functions of the nephrons is to put water back into the bloodstream to prevent dehydration. In order to accomplish that task, the antidiuretic hormone (ADH) causes various areas of the nephrons to become permeable to water. What region of the numerous nephrons is sensitive to ADH?

Answer 5

Distal convoluted tubule

Question 6

Once the nephron becomes permeable to water, water will enter into the bloodstream and therefore stay in the body. What is/are the name/s of the blood vessels that surround the nephrons?

Answer 6

Vasa recta

Question 7

In the glomerulus, these cells cover the capillaries which makes the membrane impermeable to plasma proteins and blood cells.

Answer 7

Podocytes

Question 8

The following are part of the urine formation process, EXCEPT:

Tubular Secretion
Tubular Reabsorption
Glomerular Filtration
Tubuloglomerular feedback

Answer 8

Tubuloglomerular feedback

Question 9

A thickening of smooth muscle at the bladder urethra junction which keeps the urethra closed when urine is not being passed.

Trigone
Detrusor muscle
External urethral sphincter
Internal urethral sphincter

Answer 9

Internal urethral sphincter

Question 10

Which of the following substances is/are reabsorbed by the nephrons of the kidney?

Urea
Uric acid
Glucose
Creatinine

Answer 10

Glucose

Question 11

Calcitriol, the active form of Vit. D, helps regulate calcium homeostasis, and erythropoietin stimulates the production of red blood cells. Both of these are related to which function of the kidneys.

Answer 11

Production of hormones

Question 12

Three layers of tissue surrounding your kidneys are the following EXCEPT:

Adipose capsule
Renal corpuscle
Renal fascia
Renal capsule

Answer 12

Renal corpuscle

Question 13

A condition when there is an inferior displacement or dropping of the kidney and occurs when it slips from its normal position because it is not securely held in place by adjacent organs or its covering of fat.

Answer 13

Nephroptosis

Question 14

In some kidney diseases, glomerular capillaries are damaged and become so permeable that plasma proteins enter glomerular filtrate. This in turn results to a visible sign of these patients called

Answer 14

Edema

Question 15

When blood concentration of glucose exceeds 200 mg/mL, the renal symporters cannot work fast enough to reabsorb all the glucose that enters the glomerular filtrate. This results to some glucose remaining in the urine in a condition known as

Answer 15

Glucosuria
