Acid

A hydrogen ion (H+) donor

2

Base

A hydroxyl ion (OH-) donor

3

A buffer system _________ the pH ____________.

minimizes
change

4

There are 3 chemical acid-base buffer systems found in the blood:

-Carbonic Acid/Bicarbonate Buffer System
-Phosphate Buffer System
-Protein Buffer System

5

_______________ ______________ system is the most abundant and can act as either acids or bases.

Protein Buffer

6

Two types of acidosis

Respiratory and Metabolic

7

Respiratory Acidosis

too much CO2 in blood cause by injury to brain stem-decreased rate and depth of breathing
emphysema, pneumonia

8

Metabolic Acidosis

Accumulation of acids (non-respiratory) or loss of bases
uremia, Prolonged diarrhea

9

Compensation for respiratory acidosis?

metabolic alkalosis

10

Compensation for metabolic acidosis?

Respiratory alkalosis

11

Two types of alkalosis

Metabolic and respiratory

12

Respiratory Alkalosis

Too little carbon dioxide in blood due to hyperventilation caused by anxiety; salicylate poisoning

13

Compensation for Respiratory Alkalosis?

Metabolic Acidosis

14

Metabolic Alkalosis

Excessive loss of hydrogen ions or a gain in bases
vomiting, excessive intake of alkaline drugs

15

A pH of 7 is __________.

neutral

16

The lower the pH number, the ________ acidity of a solution.

greater

17

The higher the pH number, the _________ hydrogen ion concentration, which indicates a _________ solution.

lower
basic

18

6 or lower pH =

acidic, greater H+

19

8 or higher pH =

basic/alkaline, less H+

23

Baking soda pH

basic

24

Distilled water pH

neutral

25

Two body systems assist in the regulation of blood pH

-Urinary (renal) System
-Respiratory System

26

An increased pCO2 results in a _________ (acidic) blood pH.

low (high acidity)

27

A decreased pCO2, results in a high (_____) blood pH.

basic

28

Acidosis occurs when the pH of blood drops below ________.

7.35

29

Urinary system

Metabolic acidosis

30

6.80 to 7.35

acidosis

31

7.35 to 7.45

normal

32

below 6.80

death

33

7.45 to 7.80

alkalosis

34

above 7.80

death

35

In the healthy adult, the pH is between

7.35 and 7.45
