1

Pertaining to kidney

renal, nephro

2

Absence of urine formation by kidneys

anuria

3

Only scant amount of urine produced

oliguria

4

Excessive urination

polyuria

5

Two whats and one what (ureter/urethra)

Two ureters, one urethra

6

Kidneys filder blood to produce urine by

Blood filtration/absorption/secretion, fluid balance regulation, acid-base balance & regulation, hormone production

7

Which kidney is located more cranially

Right

8

Located where in relation to abdominal cavity

Retropetironeal (outside parietal peritoneum)

9

Kidneys bean shaped, except lobulated in

Cattle

10

What enters the hilus

Blood, lymph vessels, ureters enter & leave kidney

11

Layers of ureters

Outer fibrous, middle (smooth) muscle, inner (transitional) epithelial

12

Angle that ureters enter urinary bladder

Oblique, prevents urine from backing up into the ureter being that it collapses if the bladder is full

13

Bladder composed of what two parts

Muscular sac, neck

14

Urination, micturition, and uresis all describe

Urine from bladder - urethra- out of body

15

2 step process of urination

Urinary bladder constantly accumulates urine. Trigger point eventually reached, spinal reflex is activated that returns the motot impulse to the bladder muscles and causes them to contract

16

Describe female urethra

Short, straight, wide

17

Describe male urethra

Long, curved

18

Uroliths common in what animals

Cattle, sheep, goats, cats, dogs

19

Convoluted means

Twisted

20

Fenestrations means

Small holes/ pores

21

Majority of nephron located where

Renal cortex portion of kidney

22

Renal corpuscle composed of what, does what

Glomerulus & Bowman's capsule, filters blood

23

Allows fluid and water soluble waste to leave blood and enter the nephron

Glomerulus

24

Holds fluid/waste filtered out of blood

Bowman's capsule

25

Continuation of Bowman's capsule, follows a convoluted path through renal cortex

Proximal convoluted tubule

26

Between the convoluted tubules, descends into medulla of the kidney then makes a U-turn and goes back to the cortex

Loop of Henle

27

Continuation of Loop of Henle

Distal convoluted tubule

28

Distal convoluted tubule dumped into the collecting ducts that carry filtrate through medulla and then empty into the

Renal pelvis, leads to ureter

29

Up to what % of blood goes to the kidneys

25%

30

All circulating blood passes through the kidneys in how many minutes

4-5 minutes
