← Human Body & HealthWhich consequence results when hemoglobin's saturation capacity decreases significantly, decreasing transport?
A)Reduced systemic oxygen delivery✓
B)Increased carbon dioxide exhalation
C)Decreased pulmonary blood flow
D)Elevated bicarbonate buffer production
💡 Explanation
Reduced hemoglobin saturation disrupts oxygen transport via hemoglobin binding because less oxygen binds to red blood cells at the lungs. Therefore, systemic oxygen delivery diminishes, rather than altering CO2 exhalation, blood flow, or buffer creation under normal ventilation and metabolic rates.
