A hydrogen ion (H+) donor
A hydroxyl ion (OH-) donor
A buffer system _________ the pH ____________.
There are 3 chemical acid-base buffer systems found in the blood:
-Carbonic Acid/Bicarbonate Buffer System
-Phosphate Buffer System
-Protein Buffer System
_______________ ______________ system is the most abundant and can act as either acids or bases.
Two types of acidosis
Respiratory and Metabolic
too much CO2 in blood cause by injury to brain stem-decreased rate and depth of breathing
Accumulation of acids (non-respiratory) or loss of bases
uremia, Prolonged diarrhea
Compensation for respiratory acidosis?
Compensation for metabolic acidosis?
Two types of alkalosis
Metabolic and respiratory
Too little carbon dioxide in blood due to hyperventilation caused by anxiety; salicylate poisoning
Compensation for Respiratory Alkalosis?
Excessive loss of hydrogen ions or a gain in bases
vomiting, excessive intake of alkaline drugs
A pH of 7 is __________.
The lower the pH number, the ________ acidity of a solution.
The higher the pH number, the _________ hydrogen ion concentration, which indicates a _________ solution.
6 or lower pH =
acidic, greater H+
8 or higher pH =
basic/alkaline, less H+
Lemon juice pH
Baking soda pH
Distilled water pH
Two body systems assist in the regulation of blood pH
-Urinary (renal) System
An increased pCO2 results in a _________ (acidic) blood pH.
low (high acidity)
A decreased pCO2, results in a high (_____) blood pH.
Acidosis occurs when the pH of blood drops below ________.
6.80 to 7.35
7.35 to 7.45
7.45 to 7.80
In the healthy adult, the pH is between
7.35 and 7.45
