Chapter 10: Blood Cells And Functions - Quiz

The main cells in the human body are the red and white blood cells. The red blood cells are charged with carrying oxygen from the lungs to the body tissues and carbon dioxide as a waste product from the tissues to the lungs. The white blood cells however are charged with protecting the body against foreign invaders. Test out what you understood about blood cells and their functions in the body from chapter ten.


Questions and Answers
  • 1. 

    What are the three formed elements of blood?

    • A.

      Spleen, tonsils, thymus

    • B.

      Erythocytes, thrombocytes, leukocytes

    • C.

      A, B, O

    • D.

      Platelets, basophil, monocyte

    Correct Answer
    B. Erythocytes, thrombocytes, leukocytes
    Explanation
    The three formed elements of blood are erythrocytes (red blood cells), thrombocytes (platelets), and leukocytes (white blood cells). Erythrocytes are responsible for carrying oxygen to the body's tissues, thrombocytes play a crucial role in blood clotting to prevent excessive bleeding, and leukocytes are involved in the immune response, defending the body against infections and diseases.

  • 2. 

    What Transports oxygen and carbon dioxide has a lifespan of 80-120 days and and there are  approximately 5 million per cubic meter? 

    • A.

      Erythrocytes

    • B.

      Thrombrocytes

    • C.

      Leukocytes

    • D.

      Monocytes

    Correct Answer
    A. Erythrocytes
    Explanation
    Erythrocytes, also known as red blood cells, are responsible for transporting oxygen and carbon dioxide in the body. They have a lifespan of 80-120 days and there are approximately 5 million of them per cubic meter.

    Rate this question:

  • 3. 

    Which blood cells clots blood  and have 200k - 500k in the human body? 

    • A.

      Erythrocytes

    • B.

      Thrombocytes

    • C.

      Leukocytes

    • D.

      Neutrophill

    Correct Answer
    B. Thrombocytes
    Explanation
    Thrombocytes are blood cells that are responsible for clotting blood. They help in the formation of blood clots to prevent excessive bleeding. The normal range of thrombocytes in the human body is between 200,000 and 500,000. Erythrocytes, leukocytes, and neutrophils are not directly involved in blood clotting.

    Rate this question:

  • 4. 

    Which blood cells provides the bodies main defense against invading pathogens?

    • A.

      Erythrocytes

    • B.

      Thrombocytes

    • C.

      Leukocytes

    • D.

      T-cells

    Correct Answer
    C. Leukocytes
    Explanation
    Leukocytes, also known as white blood cells, provide the body's main defense against invading pathogens. They play a crucial role in the immune system by identifying and destroying foreign substances such as bacteria, viruses, and other harmful microorganisms. Unlike erythrocytes (red blood cells) and thrombocytes (platelets) which are primarily involved in oxygen transport and blood clotting respectively, leukocytes are specifically designed to combat infections and maintain overall health. T-cells, a type of leukocyte, are particularly important in coordinating the immune response and targeting infected cells.

    Rate this question:

  • 5. 

    What are the four blood types? 

    • A.

      Red, white, rose-colored, orange

    • B.

      Erythrocytes, thrombocytes, leukocytes, neutrophils

    • C.

      A, B, AB, O

    • D.

      Plasma, lymphocytes, monocytes, red blood cells (RBC)

    Correct Answer
    C. A, B, AB, O
    Explanation
    The four blood types are A, B, AB, and O. These blood types are determined by the presence or absence of certain antigens on the surface of red blood cells. Blood type A has A antigens, blood type B has B antigens, blood type AB has both A and B antigens, and blood type O has neither A nor B antigens. The presence or absence of these antigens is important for blood transfusions to ensure compatibility between the donor and recipient.

    Rate this question:

  • 6. 

    Which system  1) Returns fluid from tissue spaces to the blood stream? 2) protects the body against pathogens? 3) serves as a pathway for the absorption of fat?

    • A.

      Circulatory system

    • B.

      Nervous system

    • C.

      Respiratory system

    • D.

      Lymphatic system

    Correct Answer
    D. Lymphatic system
    Explanation
    The lymphatic system returns fluid from tissue spaces to the blood stream through the lymphatic vessels. It also plays a crucial role in protecting the body against pathogens by filtering and trapping them in lymph nodes. Additionally, the lymphatic system serves as a pathway for the absorption of fat from the digestive system into the bloodstream.

    Rate this question:

  • 7. 

    The spleen, tonsils and thymus are all accessories of what system? 

    • A.

      Circulatory system

    • B.

      Muscular system

    • C.

      Digestive system

    • D.

      Lymphatic system

    Correct Answer
    D. Lymphatic system
    Explanation
    The spleen, tonsils, and thymus are all part of the lymphatic system. The lymphatic system is responsible for producing and transporting lymph, a fluid that helps remove toxins, waste, and other unwanted substances from the body. The spleen acts as a filter for the blood and helps in the production of white blood cells. The tonsils and thymus are involved in the immune response, helping to protect the body against infections. Therefore, these organs are all accessories of the lymphatic system.
