Explaining muscles by spaghetti noodles, ABG by go fish and acid-base by Pizza all sounds interesting . It can be confusing to students as well. Alllowing students to feel their own muscles...showing them what is acidic (lemons)and what is alkaline (Vinegar ) also helps...Learning a few things can help: Normal ph 7.35-7.45
metabolic: high ph/high O2=alkalosis
Metabolic: low PH/ Low O2=acidosis
Respiratory: Low ph/ High Co2= acidosis
Respiratory: High ph/ low Co2=alkalosis
