Blood Components and Oxygen Transport

Steps:

• Identify the blood component that transports oxygen: red blood cells (erythrocytes) via hemoglobin.
• Recall standard blood composition: red blood cells comprise 44% of total blood volume.
• Match to pie chart percentages: the 44% slice represents red blood cells.
• Conclude that 44% is the volume for oxygen transport.

Why C is correct:

• Red blood cells, which carry oxygen-bound hemoglobin, make up 44% of blood volume per standard hematology.

Why the others are wrong:

• A: 1% represents white blood cells or platelets, which fight infection or aid clotting, not oxygen transport.
• B: 30% is not a standard blood component percentage.
• D: 55% is plasma, which carries nutrients and waste but not oxygen primarily.

Final answer: C
