In the ABO blood typing system, which antibodies does blood type A have in the plasma?
Anti-A antibodies
ExplanationBlood type A individuals possess antibodies against the B antigen.
#14
Which medical condition is characterized by the excessive production of red blood cells?
Polycythemia
ExplanationPolycythemia leads to an increased number of circulating red blood cells.
#15
Which blood disorder is characterized by an abnormal increase in the number of white blood cells?
Leukemia
ExplanationLeukemia involves uncontrolled proliferation of white blood cells, disrupting normal blood function.
#16
What is the medical term for the process of blood cell formation in the bone marrow?
Hematopoiesis
ExplanationHematopoiesis generates all blood cell types from hematopoietic stem cells.
#17
Which blood disorder is characterized by the inability of blood to clot properly?
Hemophilia
ExplanationHemophilia results in prolonged bleeding due to deficient clotting factors.
