acids to what to hydrogen
bases do what to hydrogen
Acids- release hydrogen in solution
Base- accepts hydrogen in solution
low ph=what=how much hydrogen //levels
high ph=what=how much hydrogen //levels
Low pH = acidic-more hydrogen-<7.35
High pH = alkaline-less hydrogen >7.45
Volital acids

such as carbonic acid from lungs
Non volital acids

Body has 3 different systems to maintain normal pH
Buffer system-in the fluids
Respiratory system
Renal system
buffer system
what does it do
prevent major changes in pH by either removing or adding H ions-
When acidic buffer system
- binds with hydrogen to minimize ph change
When alkalotic- buffer system
releases hydrogen ions and restores ph
repository system does what
how fast
Regulates levels of carbonic acid (CO2-
works quickly
respiratory system in metabloic acidosis
rr and depth of lung increases to relase co2
respiratory system in metabolic alkalosis
