Question

___________ is a condition in which the oxygen-carrying capacity of the blood is reduced; it is a sign, not a diagnosis and is usually characterized by a decreased erythrocyte count or hemoglobin deficiency. Kinds include iron-deficiency, pernicious, hemorrhagic, hemolytic, Thalassemia, and aplastic.

Answer 1

Anemia is a condition where the blood's oxygen-carrying capacity is diminished due to various causes, such as deficiency in iron or vitamin B12, excessive blood loss, or genetic disorders. It presents with symptoms like fatigue and shortness of breath and is diagnosed by evaluating blood cell production and morphology.

Step-by-step explanation:

Anemia is a condition characterized by a reduced oxygen-carrying capacity of the blood, typically due to a decrease in erythrocyte count or hemoglobin levels. There are various types of anemia, each with different causes and characteristics, such as iron-deficiency anemia, pernicious anemia, hemorrhagic anemia, hemolytic anemia, Thalassemia, and aplastic anemia. Iron-deficiency anemia is caused by a lack of sufficient iron for hemoglobin production, which is necessary for oxygen binding and transport.

Pernicious anemia arises from a deficiency in vitamin B12, crucial for red blood cell production. Hemorrhagic anemia occurs due to excessive blood loss. Hemolytic anemia results from the accelerated destruction of red blood cells. Thalassemia is a genetic disorder affecting hemoglobin production, and aplastic anemia involves the inability of the bone marrow to produce adequate numbers of red blood cells.
