1
Q

waht is the normal color of urine

A

pale yellow

2
Q

what kind of things can alter the color of urine

A

hydration levels. certain drugs, supplements or foods

3
Q

what is the normal PH or urine

A

between 4 and 8 with an average of 6. typically acidic to prevent the growth of bacteria.

4
Q

specific gravity of urine

A

always higher than water which is 1. so more than 1. the range is 1.001 - 1.006

5
Q

the higher the specific gravity the more particles in the urine

A

T

6
Q

as time goes on urine has a stronger smell, why?

A

because the bacteria is breaking it down and making amonia

7
Q

what things should not be in urine

A

RBC, WBC and large proteins becuase they are too large to get across the filtration membrane. Also glucose should not be in urine

8
Q

things that should be in urine besides water

A

electrolytes, sodium, chloride, potassium, phosphate, bicarbonate, ammonia, uric acid, urea, small proteins and amino acids

9
Q

what is the definition of PH

A

measures free hydrogen ions on a scale of 0-14

10
Q

As you increase the number of free hydrogen ions the PH goes

A

DOWN

11
Q

A PH of 7 means that the solution is

A

neutral

12
Q

Ph less than 7 means the solution is

A

acidic

13
Q

PH more than 7 means the solution is

A

basic

14
Q

if you have hyperventilation what will happen to your PH

A

Less Co2, Less free hydrogen and PH goes up

15
Q

An acid will increase the free hydrogen and a base will remove free hydrogen

A

True

16
Q

a buffer resists change in PH to keep the PH

A

constant.

17
Q

The location of the kidneys are

A

retroperitoneal.

18
Q

kidney has a connective tissue capsule called the

A

renal capsule layer

19
Q

indent on the kidney is called a hillus or hillum where

A

renal artery, vein and ureter

20
Q

outer area of kidney is teh

A

cortex

21
Q

inner area of kidney is called the

A

medulla

22
Q

The direction of urine production is

A

from the cortex to the medulla and out the ureter

23
Q

medulla or renal pyramid has a tip called the

A

papilla

24
Q

renal columns are the spaces between the

A

pyramids.

25
Q

structural and functional unti of the kidney

A

nephron

26
Q

nephron is a tube thta the urine is moving through

A

true

27
Q

capillary beds are around the nephron to

A

reabsorb the water back into the blood

28
Q

where is the blood filtered

A

renal corpusal

29
Q

capillary bed in the renal corpusal

A

glomerulus

30
Q

outer area of the glomerulus is the

A

bowmans capsule

31
Q

order of the glomerulus

A

renal corpusul, pct, descending limb of the loop of henley, ascending limb of the loop of henley, dct, collecting duct

32
Q

Afferent bring blood in

A

efferent brings blood out

33
Q

The capillary bed that wraps around the top is the

A

peritubular capillaries

34
Q

the capillary bed that wraps around the loop of henley is the

A

vaso rectus

35
Q

podocytes form a barrier to

A

prevent large molecules from leaving the blood and getting into the urine

36
Q

the space of the renal corpusul is the

A

bowmans space
