B)Fluid shift
C)Diffusion
D)Concentration gradient

Question

Quizplus · Accepted Answer

Oxygen therapy is effective when oxygen enters the blood through the physiological process of diffusion. Diffusion occurs when molecules move from an area of higher concentration to an area of lower concentration, which is the case with oxygen moving from the lungs into the bloodstream to be transported to the body's tissues. Osmosis and fluid shift refer more specifically to the movement of water molecules, while a concentration gradient refers to the difference in concentration between two areas. Therefore, option C) diffusion is the correct answer.
