Which condition is caused by an insufficient number of red blood cells, hemoglobin or blood volume?

• A. Anemia
• B. Angina pectoris
• C. Alkalosis
• D. Arteriosclerosis

Answer: (A)

When the blood can’t transport enough oxygen because there aren’t enough red blood cells or there isn’t enough hemoglobin in them, the result is anemia. This reduced oxygen-carrying capacity makes tissues receive less oxygen, leading to symptoms like fatigue and shortness of breath. The other conditions described are different: angina pectoris is chest pain caused by insufficient blood flow to the heart muscle, alkalosis is an imbalance in body pH toward the basic side, and arteriosclerosis is the thickening and hardening of artery walls. So the description given fits anemia, the condition defined by a drop in red blood cells or hemoglobin that lowers the blood’s ability to deliver oxygen.
