What is anemia?

• A. A condition characterized by excessive white blood cells
• B. A condition characterized by deficiency of red blood cells or hemoglobin
• C. A condition that increases blood clotting
• D. A disease affecting the bone marrow function

Answer: (B)

Anemia is defined as a condition characterized by a deficiency of red blood cells or hemoglobin. This deficiency results in a reduced capacity of the blood to carry oxygen to tissues throughout the body. Hemoglobin is the protein in red blood cells that binds to oxygen, and when its levels are low, or when there is a reduced number of red blood cells, the body may not receive sufficient oxygen. This can lead to symptoms such as fatigue, weakness, and pallor, among others. Understanding anemia's role in overall health is critical. It can be caused by various factors, including nutritional deficiencies (such as iron, vitamin B12, or folic acid), chronic diseases, bone marrow disorders, or blood loss. Recognizing the definition of anemia helps in identifying its underlying causes and implementing appropriate treatments or interventions.
