Which term refers to a condition where the body's blood lacks enough healthy red cells or hemoglobin?

• A. Anemia
• B. Alzheimer's Disease
• C. Bronchitis
• D. Angina

Answer: (A)

Anemia is a condition in which the blood doesn’t have enough healthy red blood cells or enough hemoglobin, the part of red blood cells that carries oxygen. When there aren’t enough cells or the hemoglobin isn’t present in sufficient amounts, the body’s tissues don’t receive enough oxygen, leading to tiredness, weakness, pale skin, and shortness of breath. The other terms describe different health issues that aren’t about the blood’s oxygen-carrying capacity: Alzheimer’s disease affects the brain, bronchitis involves inflammation of the airways, and angina is chest pain from reduced blood flow to the heart.
