Homeostasis of Acids and Bases Flashcards
what is pH? and normal pH level?
measure of acidity, 7.35-7.45
what is an Acid?
compound that gives up H+, donor
what is a base?
compound that binds to H+, acceptor
what are the two types of acids?
volatile (easy to gas) non volatile ( doesnt turn to gas)
what are the sources of H+?
carbohydrates, fats and proteins
what are the 3 mechanisms to regulate pH?
buffer, respiratory(co2), renal (urination)
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
what are the 3 buffer systems?
protein, phosphate, carbonic acid-bicarbonate
where does carbonic acid-bicarbonate occur and what regulates it?
ICF and ECF by lungs and kidneys
strong acids are neutralized by?
bicarbonate= +carbonic acid
strong bases are neutralized by?
carbonic acid=+bicarbonate
why is blood more basic?
acids (CO2 waste) are continuously being created within blood
non volatile metabolic reactions are regulated through?
urination
what make bicarbonate?
kidneys
acidosis is when?
pH levels are -7
