1. BILL pH Homeostasis

2. ASTHMA (CAUSES ACIDOSIS)
Decreased breathing ↑ CO2 in blood shifts equilibrium will shift to left Increases HCO3– and H+ ions (pH decreases)
WHAT WILL ORGANS DO? Kidneys will excrete more HCO3- Respiratory therapy helps remove CO2

3. REPEATED VOMITING due to illness (ALKALOSIS)
Increases HCO3 – and H+ ions (pH decreases)
WHAT WILL ORGANS DO? Kidneys will excrete less HCO3- Decreased respiration = less CO2 REMOVED

4. ANXIETY/HYPERVENTILATION (ALKALOSIS)
INCREASED breathing ↓ CO2 in blood shifts equilibrium to right decreases HCO3 – and H+ ions (pH increases)
WHAT WILL ORGANS DO? Fainting slows breathing (less CO2 removed) Kidneys will excrete less HCO3-

5. HEAVY EXERCISE/SEVERE BURNS (CAUSES ACIDOSIS)
O2 shortage = more fermentation (reduced blood volume ↓ O2 to tissues) Release of acidic byproducts (lactic acid) ↑ H+ pH ↓
Equilibrium will shift to right
WHAT WILL ORGANS DO? Kidneys will excrete MORE HCO3- INCREASED breathing to remove CO2

6. DIABETES (CAUSES ACIDOSIS)
If cells can’t take in glucose for respiration=more fermentation Release of acidic byproducts (lactic acid) ↑ H+ pH ↓
Equilibrium will shift to right
WHAT WILL ORGANS DO? Kidneys will excrete MORE HCO3- INCREASED breathing will remove CO2
