gerald is lightheaded and tired from a lack of oxygen in his tissues. what is most likely the reason he feels this way?\n○ his plasma level is high.\n○ his white blood cell count is high.\n○ his platelet count is low.\n○ his red blood cell count is low.
Answer
Brief Explanations:
Red blood cells carry oxygen. A low red - blood cell count means less oxygen is transported to tissues, causing light - headedness and tiredness. High plasma level, high white blood cell count, and low platelet count are not directly related to oxygen - carrying capacity.
Answer:
His red blood cell count is low.
