(36 cards)
When hydrogen goes up pH goes
down
When hydrogen goes down pH goes
up
what is the most acidic acid made by the body?
hydrochloric acid, by the stomach
Acids have ___ H+ ions and can ____ them
more, donate
Bases have ____ H+ and give up hydroxide ion ____
less, OH-
strong acids _____ completely
dissociate
Weak acids dissociate ______
partially
hydrogen is a component of
sugars
proteins
starch
fats
what does hydrogen do in the body?
maintains cell membranes, enzyme activity, keeps body hydrated, energy production
what is the normal range of pH
7.35-7.45
if HCL is found outside the body what can it cause?
damage
duodenum has defense mechanisms to ______ acid
neutralize
Lower Esophageal Sphincter _____ movements of acid into the _____
prevents, esophagus
What electrolytes are effected by acid-base balance?
sodium, potassium, chloride
volatile acids
can be converted to gas
excreted/eliminated by lungs
HCO3
non-volatile acids
eliminated by kidney’s, except lactic acid (kidney and liver)
lactic acid, phosphoric acid, sulfuric acid, acetoacetic acid, beta-hydroxybutyric acid
what is a survivable range of pH
7.2-7.5/6
3 main types of buffer systems
bicarbonate-carbonic acid buffer
phosphate buffer
protein buffer
what are buffers?
chemicals in body that combine with acid or base to change pH
almost instantaneous, short lived
bicarb-carbonic acid
located in ECF
phosphate buffer
main intracellular buffer
cannot measure
protein buffers
nearly all proteins can function as buffers
carboxyl group
amino acid
acetic acid
respiratory mechanisms
only work on volatile acids
exhalation excretes carbonic acid
what happens to RR and depth during alkalosis
body holds onto acids RR and Depth decrease
