Urinary

Question 1

Functions of urinary system

Answer 1

• excretion
• blood volume and blood pressure control
• pH regulation
• concentration of solutes
• vitamin D production
• RBC concentration

Question 2

Renal corpuscle

Answer 2

structure that contains Bowman’s capsule and glomerulus

Question 3

Bowman’s capsule

Answer 3

• opens into proximal tubule

- contains podocytes (specialized cells around glomerular capillaries

Question 4

Glomerulus

Answer 4

contains capillaries wrapped around

Question 5

Filtrate

Answer 5

• fluid that passes across filtration membrane

- found in capsular space (space between Bowman’s capsule and glomerular capillaries)

Question 6

Filtration membrane

Answer 6

• in renal corpuscle

- includes glomerular capillaries, podocytes, basement membrane

Question 7

Loop of Henle

Answer 7

water and solutes pass through thin walls by diffusion

Question 8

Collecting duct

Answer 8

• empties into calyces

- carry fluid from cortex through medulla

Question 9

Flow of filtrate through nephron

Answer 9

1) Renal corpuscle
2) Proximal convoluted tubule
3) Descending loop of Henle
4) Ascending loop of Henle
5) Distal convoluted tubule
6) Collecting duct
7) Calyx (minor then major)
8) Renal pelvis
9) Ureter

Question 10

Blood flow through kidney

Answer 10

1) Renal artery
2) Intermediate arteries
3) Afferent arteriole
4) Glomerulus
5) Efferent arteriole
6) Peritubular capillaries
7) Vasa recta
8) Intermediate veins
9) Renal vein

Question 11

Filtration pressure

Answer 11

• influenced by blood pressure
• forces fluid across filtration membrane
• formation of filtrate depends on filtration pressure
