Define anemia Anemia is a decrease in the oxygen-carrying ability of the blood.
Give 3 possible causes of anemia iron deficiency folic acid deficiency vitamin b12 deficiency vitamin cdeficiency autoimmune induced hemolytic anemia due to chronic infection some inherited causes like thalasemia and sickle cell anemia acute like surgery and chronic blood lose like stoma
