A. Bound to the globin portion of hemoglobin: Oxygen binds the heme (iron) portion, not the globin protein chains
B. Dissolved in the plasma: Only a small fraction (~1.5%) of O₂ is dissolved in plasma
C. Bound to the heme portion of hemoglobin: Most O₂ (~98–99%) is carried as oxyhemoglobin bound to heme iron
D. In the form of bicarbonate and water: Bicarbonate transport applies to CO₂, not O₂
Correct Answer is B
Explanation
A. pressure of the blood: Not primarily—systemic blood pressure is mainly from cardiac output and vascular resistance; proteins contribute minimally.
B. osmotic: Plasma proteins (especially albumin) generate colloid osmotic/oncotic pressure that pulls fluid into capillaries.
C. filtration: They oppose filtration by favoring reabsorption (their oncotic pull counters hydrostatic push).
D. central venous: CVP reflects blood volume, venous tone, and right heart function, not plasma protein levels directly.
E. hydrostatic: Hydrostatic pressure is due to fluid column and pumping; proteins affect oncotic, not hydrostatic, pressure.
