Physiological vs

Physiological buffers are only found in the respiratory system, while chemical buffers are found in the renal system

Physiological buffers act faster than chemical buffers but have less capacity

Physiological buffers act more slowly than chemical buffers but have more capacity (correct)

Physiological buffers are only effective in resisting pH changes from strong acids, while chemical buffers resist pH changes from strong bases

Phosphate buffer system

Bicarbonate buffer system

Protein buffer system

Carbon dioxide buffer system (correct)

Bicarbonate ion picks up a H+ ion and becomes carbonic acid, increasing H+ ions and lowering pH

Carbonic acid donates a H+ ion and becomes the bicarbonate ion, decreasing H+ ions and raising pH

Bicarbonate ion picks up a H+ ion and becomes carbonic acid, decreasing H+ ions and raising pH
