Blood Knowledge Quiz - Quiz

Are you ready for the blood knowledge quiz? Nearly seven percent of a human's body weight is made up of blood; the blood consists of white blood cells and red blood cells, which perform a specific function in the body. This quiz should be a simple review of most of the topics from this chapter. Give it a shot and get back on your notes on the topics you identify as not clearly understood.


Questions and Answers
  • 1. 

    The protein found in the blood that is responsible for transporting oxygen is

    • A.

      Erythropoietin

    • B.

      Hemoglobin

    • C.

      Gamma globulin

    • D.

      None of these

    Correct Answer
    B. Hemoglobin
    Explanation
    Hemoglobin is the correct answer because it is a protein found in red blood cells that binds to oxygen molecules and transports them throughout the body. It has a high affinity for oxygen, allowing it to efficiently carry oxygen from the lungs to the tissues and organs. Erythropoietin is a hormone that stimulates the production of red blood cells, gamma globulin is a type of antibody, and none of these options specifically transport oxygen like hemoglobin does.

    Which is not a granulocyte?

    • A.

      Neutrophil

    • B.

      Basophil

    • C.

      Leucocyte

    • D.

      None of these

    Correct Answer
    C. Leucocyte
    Explanation
    A granulocyte is a type of white blood cell that contains granules in its cytoplasm. Neutrophils and basophils are both types of granulocytes. Leucocyte, on the other hand, is a general term for white blood cells, which includes both granulocytes and agranulocytes. Therefore, leucocyte is not a specific type of granulocyte.

  • 3. 

    The proteins of the blood are formed by the

    • A.

      Kidney

    • B.

      Bone

    • C.

      Heart

    • D.

      Liver

    Correct Answer
    D. Liver
    Explanation
    The liver is responsible for producing proteins in the blood. It synthesizes various proteins, including albumin, clotting factors, and transport proteins. These proteins play crucial roles in maintaining the body's overall health and function. The liver also helps in detoxification and metabolism, making it a vital organ for protein production and other essential functions in the body.

    Rate this question:

  • 4. 

    What characteristic of platelets makes them well suited for their function?

    • A.

      Sticky

    • B.

      Small

    • C.

      Full cell complement

    • D.

      Huge

    Correct Answer
    A. Sticky
    Explanation
    Platelets are well suited for their function due to their sticky characteristic. This allows them to adhere to damaged blood vessels and form clots, preventing excessive bleeding. The stickiness of platelets enables them to aggregate together and form a plug at the site of injury, promoting the healing process. Additionally, their small size allows them to easily navigate through narrow blood vessels and reach the site of injury efficiently. The full cell complement and huge size options are incorrect as platelets are actually small cell fragments rather than full cells, and they are not considered large in size.

    Rate this question:

  • 5. 

    The substance that stimulates the formation of white blood cells is

    • A.

      Erythropoietin

    • B.

      Thrombopoietin

    • C.

      Colony-stimulating factors

    • D.

      None of these

    Correct Answer
    C. Colony-stimulating factors
    Explanation
    Colony-stimulating factors are substances that stimulate the formation and maturation of white blood cells in the body. They are produced by various cells in the bone marrow and play a crucial role in regulating the production of different types of white blood cells, such as granulocytes, monocytes, and lymphocytes. These factors are important for maintaining a healthy immune system and fighting off infections. Erythropoietin and thrombopoietin, on the other hand, are substances that stimulate the production of red blood cells and platelets, respectively. Therefore, the correct answer is colony-stimulating factors.

  • 9. 

    Erythrocytes are flattened because

    • A.

      Otherwise, they would not fit through the vessels

    • B.

      They have been compressed by the larger white blood cells

    • C.

      The depression is where oxygen attaches

    • D.

      Organelles eject during maturation

    Correct Answer
    D. Organelles eject during maturation
    Explanation
    During the maturation process of erythrocytes, organelles are ejected from the cell. This is necessary for the cell to become specialized and carry out its main function, which is to transport oxygen. By removing the organelles, the cell becomes flattened and takes on its characteristic biconcave shape. This shape allows the erythrocytes to fit through the narrow vessels in the circulatory system, ensuring efficient oxygen delivery to tissues throughout the body.

    If the D antigen is present, blood is

    • A.

      +

    • B.

      -

    • C.

      Fatal

    • D.

      =

    Correct Answer
    A. +
    Explanation
    If the D antigen is present in blood, it means that the blood is Rh positive. Rh positive blood can be transfused to individuals who are Rh positive or Rh negative, making it compatible with a larger population. Therefore, the presence of the D antigen is not fatal and does not cause any harm to the recipient.

    Rate this question:

  • 11. 

    When a blood vessel is damaged, this hormone is needed to constrict blood vessels to reduce blood loss.

    • A.

      Serotonin

    • B.

      Thromboplastin

    • C.

      Fibrinogen

    • D.

      Thrombin

    Correct Answer
    A. Serotonin
    Explanation
    Serotonin is a hormone that is needed to constrict blood vessels when they are damaged in order to reduce blood loss. When a blood vessel is injured, serotonin is released, causing the smooth muscles in the blood vessel walls to contract, narrowing the blood vessel and reducing the flow of blood. This constriction helps to minimize blood loss and allows the body to initiate the clotting process to repair the damaged vessel.

    • A.

      A and AB

    • B.

      B and AB

    • C.

      O and AB

    • D.

      A and O

    Correct Answer
    D. A and O
    Explanation
    Type A blood can receive donations from individuals with blood types A and O. This is because type A blood has antigens on its surface that can accept antibodies from type A and type O blood. Type A blood cannot receive donations from individuals with blood types B or AB because the antibodies present in type A blood would react with the antigens present in type B or type AB blood.

    Rate this question:

  • 15. 

    In the black US population, 2 blood types are found in near equal percentages.  Those 2 blood types are
