pH balance
- pH↓ = ↑[H+]
- Buffers?
- Carbonic acid/bicarbonate buffer (ECF and RBCs)
CO2 + H2O←H2CO3 ← H+ + HCO3-
- Plus: increase respiration rate to remove CO2
- Plus: increase respiration rate to remove CO2
- Haemoglobin Buffer (RBCs)
HbO2 + H+ → Hb-H+ + O2
- Protein Buffer (ICF and plasma)
- Kidneys (ammonia buffer) -
more H+ excreted in
urine (slow to respond!)
- Carbonic acid/bicarbonate buffer (ECF and RBCs)
CO2 + H2O←H2CO3 ← H+ + HCO3-
- Buffers?
- pH ↑ = ↓ [H+]
- Buffers?
- Carbonic acid/bicarbonate buffer (ECF and RBCs)
CO2 + H2O → H2CO3 → H+ + HCO3-
- Plus: decreased respiration to retain CO2
- Plus: decreased respiration to retain CO2
- Haemoglobin buffer (RBCs)
HbO2 + H+ ← Hb-H+ + O2
- Protein buffer (ICF and plasma)
- Kidneys - retain more H+ in blood
or remove more HCO3- (slow!)
- Carbonic acid/bicarbonate buffer (ECF and RBCs)
CO2 + H2O → H2CO3 → H+ + HCO3-
- Buffers?
- Acidosis? (pH blood < 7.35)
- Respiratory Acidosis
- Metabolic acidosis
- Respiratory Acidosis
- Alkalosis (pH blood > 7.45)
- Respiratory Alkalosis
- Metabolic Alkalosis
- Respiratory Alkalosis
