B) High blood pressure disrupts oxygen transport.
C) Oxyhemoglobin circulates to the body tissue.
D) All systemic oxygen is available for diffusion.
E) Adequate red blood cells are needed for oxygen transport.
A, C, E
Feedback:
Oxygen transport occurs by dissolving oxygen in the water in the plasma and combining oxygen with red blood cells (oxyhemoglobin). Normal red blood cell count is needed for oxygen transport. High blood pressure does not disrupt transport unless there is disruption in perfusion via a bleeding or occlusion. Dissolved oxygen is the only form which can diffuse across cell membranes.
