Anemia is commonly characterized by a deficiency in hemoglobin, which is the protein in red blood cells responsible for transporting oxygen throughout the body. When there is a lack of hemoglobin, the body's ability to carry oxygen is impaired, leading to symptoms such as fatigue, weakness, and pallor. Hemoglobin levels can be affected by various factors, including nutritional deficiencies (such as iron, vitamin B12, or folate), chronic diseases, or genetic disorders.

Lack of monocytes, thrombocytes, or plasma does not directly cause anemia. Monocytes are a type of white blood cell involved in the immune response, while thrombocytes, or platelets, are crucial for blood clotting. Plasma is the liquid portion of blood that carries cells, nutrients, hormones, and waste, but does not contain hemoglobin. Therefore, the correct connection to anemia arises clearly from the lack of hemoglobin.
