Match the following methods of oxygen transport with their respective percentages: O2 bound to hemoglobin | 2% Dissolved O2 | 7% Chemically bound to hemoglobin | 98% Dissolved CO2... Match the following methods of oxygen transport with their respective percentages: O2 bound to hemoglobin | 2% Dissolved O2 | 7% Chemically bound to hemoglobin | 98% Dissolved CO2 in plasma | 23%
Understand the Problem
The question presents different methods of oxygen transport and their respective percentages. The user needs to match each method with the correct percentage of oxygen transport, which involves an understanding of respiratory physiology.
Answer
O2 bound to hemoglobin: 98% | Dissolved O2: 2% | Dissolved CO2 in plasma: 7% | CO2 bound to hemoglobin: 23%
O2 bound to hemoglobin: 98% | Dissolved O2: 2% | Chemically bound CO2 as bicarbonate (not mentioned): about 70% typically | CO2 bound to hemoglobin: 23% | Dissolved CO2 in plasma: 7%
Answer for screen readers
O2 bound to hemoglobin: 98% | Dissolved O2: 2% | Chemically bound CO2 as bicarbonate (not mentioned): about 70% typically | CO2 bound to hemoglobin: 23% | Dissolved CO2 in plasma: 7%
More Information
Hemoglobin plays a crucial role in transporting oxygen by binding with it, while a small proportion is dissolved directly in the plasma. CO2 transport involves different mechanisms, including dissolving in plasma and binding to hemoglobin.
Tips
Confusing oxygen and carbon dioxide transport methods. Oxygen mainly binds to hemoglobin, while carbon dioxide is often transported as bicarbonate ions and in smaller amounts dissolved or bound to hemoglobin.
