    The production of red blood cells is know as -

    • Erythrocyte

    • Erythroblast

    • Erythropoiesis

    Correct Answer
    A. Erythropoiesis
    Explanation
    Erythropoiesis is the correct answer because it refers to the process of red blood cell production in the body. It involves the differentiation and maturation of erythroblasts into mature red blood cells. Erythrocyte refers to the mature red blood cells themselves, while erythroblast refers to the precursor cells in the process of differentiation. Therefore, erythropoiesis is the most appropriate term to describe the production of red blood cells.

    Rh incompatibility occurs when Rh-negative maternal blood is exposed to Rh-positive fetal RBCs.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Rh incompatibility occurs when Rh-negative maternal blood is exposed to Rh-positive fetal RBCs. This can happen during pregnancy or childbirth, and can cause the mother's immune system to produce antibodies against the Rh factor. These antibodies can then cross the placenta and attack the Rh-positive red blood cells in the fetus, leading to a condition called hemolytic disease of the newborn. This can result in severe anemia, jaundice, and other complications for the baby. Therefore, the statement is true.

    ABO incompatibility is more common than Rh incompatibility, is less severe, can result in RBC hemolysis, and can occur during the first pregnancy.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    ABO incompatibility occurs when a mother's blood type is different from the fetus's blood type. It is more common than Rh incompatibility, which occurs when a mother is Rh-negative and the fetus is Rh-positive. ABO incompatibility is less severe than Rh incompatibility and can result in the hemolysis of red blood cells. It can occur during the first pregnancy, whereas Rh incompatibility typically occurs in subsequent pregnancies. Therefore, the statement is true.

    Rate this question:

  • 17. 

    Sensitization of the mother's immune system to the fetus' RBCs stimulates the production of the immunoglobulin, _____ , that is transplacentally transferred to the fetus.

    • IgA

    • IgM

    • IgG

    • IgD

    Correct Answer
    A. IgG
    Explanation
    During pregnancy, the mother's immune system may become sensitized to the fetus' red blood cells. This sensitization triggers the production of immunoglobulin G (IgG), which is then transferred across the placenta to the fetus. IgG is the only immunoglobulin that can cross the placenta and provide passive immunity to the developing fetus. It helps protect the fetus from infections and plays a crucial role in the immune response during pregnancy. IgA, IgM, and IgD do not cross the placenta as readily as IgG and have different functions within the immune system.
