Flashcards in Homeostasis of Acids and Bases Deck (20):
1

what is pH? and normal pH level?

measure of acidity, 7.35-7.45

2

what is an Acid?

compound that gives up H+, donor

3

what is a base?

compound that binds to H+, acceptor

4

what are the two types of acids?

volatile (easy to gas) non volatile ( doesnt turn to gas)

5

what are the sources of H+?

carbohydrates, fats and proteins

6

what are the 3 mechanisms to regulate pH?

buffer, respiratory(co2), renal (urination)

7

what is the buffer system?

always in blood (immediate reaction), prevent rapid change, found in body fluids; turns strong acids to weak ones and turn strong bases to weak ones

8

what are the 3 buffer systems?

protein, phosphate, carbonic acid-bicarbonate

9

where does carbonic acid-bicarbonate occur and what regulates it?

ICF and ECF by lungs and kidneys

10

strong acids are neutralized by?

bicarbonate= +carbonic acid

11

strong bases are neutralized by?

carbonic acid=+bicarbonate

12

why is blood more basic?

acids (CO2 waste) are continuously being created within blood

13

non volatile metabolic reactions are regulated through?

urination

14

what make bicarbonate?

kidneys

15

acidosis is when?

pH levels are -7

16

alkalosis is when?

pH levels are +7

17

acidosis causes?

coma and death

18

alkalosis causes?

spasms and death

19

respiratory disorders disturbs?

pCO2 - parcial pressure; concentration of CO2

20

metabolic disorders disturbs?

bicarbonate concentration
