    Which of these conditions are correctly matched with their descriptions?

    • Anemia: A condition characterized by a deficiency of red blood cells or hemoglobin

    • Polycythemia: A condition characterized by an excess of red blood cells

    • Thrombocytopenia: A condition characterized by a deficiency of platelets

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Anemia is characterized by a deficiency of red blood cells or hemoglobin, polycythemia by an excess of red blood cells, thrombocytopenia by a deficiency of platelets, thrombocytosis by an excess of platelets, and septicemia is a serious bloodstream infection.

  • 4. 

    How is the structure of a red blood cell related to its function?

    • Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which O2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)

    • Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which CO2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)

    • Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which N2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)

    • Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which O2 binds, Thus helps RBC transport oxygen (O2) and nitrogen (N2)

    Correct Answer
    A. Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which O2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)
    Explanation
    The structure of red blood cells, packed with hemoglobin, allows them to bind and transport oxygen (O2) and carbon dioxide (CO2).

    Rate this question:

  • 5. 

    Does the hormone erythropoietin regulate RBC production?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Erythropoietin is a hormone produced primarily by the kidneys, and it regulates the production of red blood cells (RBCs).

    Rate this question:

  • 6. 

    What is the function of platelets?

    • They carry oxygen

    • They fight infections

    • They help in blood clotting

    • They remove waste products

    Correct Answer
    A. They help in blood clotting
    Explanation
    Platelets play a crucial role in blood clotting. They form a plug at the site of injury, preventing excessive bleeding.

    Rate this question:

  • 7. 

    What are the three primary functions of blood?

    • Transportation, Regulation, Defense

    • Transportation, Digestion, Defense

    • Transportation, Excretion, Defense

    • Transportation, Reproduction, Defense

    Correct Answer
    A. Transportation, Regulation, Defense
    Explanation
    Blood serves three primary functions: transportation (of nutrients, oxygen, hormones, and waste), regulation (of body temperature, pH, and fluid volume), and defense (against infections and bleeding).

    Rate this question:

  • 8. 

    Which of the following are steps of hemostasis?

    • Vascular spasm

    • Platelet plug formation

    • Coagulation

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Hemostasis, the process of stopping bleeding, involves three steps: vascular spasm (constriction of blood vessels), platelet plug formation (platelets stick together to form a plug at the site of injury), and coagulation (formation of a blood clot).

    Rate this question:

  • 9. 

    Where are blood cells formed?

    • Stem cells in the bone marrow (Hematopoietic stem cells)

    • Yellow Bone Marrow

    • Red Bone Marrow

    • Kidneys

    Correct Answer
    A. Stem cells in the bone marrow (Hematopoietic stem cells)
    Explanation
    Blood cells are formed from hematopoietic stem cells in the bone marrow.
