Heart Quiz: Questions On Arteries, Veins And Capillaries! - Quiz

How much do you know about the Heart, this is a trivia questions quiz on Arteries, Veins, and Capillaries! The arteries are tasked with taking blood away from the Heart while the veins bring it all back. The primary function of capillaries is the exchange of materials between the blood and tissue cells. Just how well do they work together? Take the test!


Questions and Answers
  • 1. 

    Arteries carry blood ____ the heart. 

    • A.

      Towards

    • B.

      Away from

    • C.

      Near to

    • D.

      Next to

    Correct Answer
    B. Away from
    Explanation
    Arteries carry blood away from the heart.

    Rate this question:

  • 2. 

    The blood in the arteries moves under low pressure. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The blood in the arteries moves under high pressure. This is because the arteries carry oxygenated blood away from the heart to the rest of the body. The heart pumps blood with force, causing it to flow through the arteries at a relatively high pressure.

    Rate this question:

  • 3. 

    As arteries branch out they become increasingly smaller. The smaller portion of an artery is referred to as a (an)... 

    • A.

      Vessel

    • B.

      Capillary

    • C.

      Arteriole

    • D.

      Venule

    Correct Answer
    C. Arteriole
    Explanation
    Arteries are blood vessels that carry oxygenated blood away from the heart to various parts of the body. As arteries branch out, they divide into smaller vessels called arterioles. Arterioles are responsible for regulating blood flow and controlling blood pressure. They further divide into even smaller vessels called capillaries, where the exchange of oxygen, nutrients, and waste products occurs between the blood and the surrounding tissues. Venule is not the correct answer because it refers to the small vessels that collect deoxygenated blood from the capillaries and carry it back to the heart. Therefore, the correct answer is arteriole.

    Rate this question:

  • 4. 

    The blood contained in an artery is always rich in oxygen.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Arteries carry oxygenated blood away from the heart to various parts of the body, while veins carry deoxygenated blood back to the heart. Therefore, the statement that the blood contained in an artery is always rich in oxygen is false.

    Veins and arteries are connected by 

    Correct Answer
    capillaries,Capillaries,blood capillaries
    Explanation
    Veins and arteries are connected by capillaries, which are tiny blood vessels. Capillaries play a crucial role in the circulatory system as they allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. Their small size and thin walls enable them to efficiently transport substances to and from the cells. Thus, capillaries serve as the link between the larger blood vessels, ensuring proper blood flow and nutrient delivery throughout the body.

  • 6. 

    This vessel is tiny and so narrow that blood cells can only go through in single-file. 

    • A.

      Artery

    • B.

      Vein

    • C.

      Capillary

    • D.

      Arteriole

    • E.

      Venule

    Correct Answer
    C. Capillary
    Explanation
    Capillaries are the smallest blood vessels in the body and have a very narrow diameter. They are designed to allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. The statement in the question suggests that the vessel is tiny and narrow, which aligns with the characteristics of capillaries. Additionally, the mention of blood cells going through in single-file further supports the idea of capillaries, as their narrow size only allows for one blood cell to pass through at a time.

    Rate this question:

  • 7. 

    How thick are capillaries? 

    • A.

      One cell layer thick

    • B.

      Two cell layers thick

    • C.

      Three cell layers thick

    • D.

      Four cell layers thick

    Correct Answer
    A. One cell layer thick
    Explanation
    Capillaries are the smallest blood vessels in the body, responsible for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. They are composed of a single layer of endothelial cells, which are thin and flat. This design allows for efficient diffusion of substances across the capillary walls. Therefore, capillaries are only one cell layer thick.

    Rate this question:

  • 8. 

    Which blood vessel has blood flowing at the lowest pressure?

    • A.

      Arteries

    • B.

      Veins

    • C.

      Capillaries

    • D.

      Venules

    Correct Answer
    B. Veins
    Explanation
    Veins have blood flowing at the lowest pressure compared to arteries, capillaries, and venules. This is because veins carry deoxygenated blood back to the heart, and the pressure decreases as the blood moves away from the heart. The walls of veins are thinner and less muscular than arteries, allowing them to expand and accommodate larger volumes of blood. Additionally, veins have valves that prevent the backflow of blood, further reducing the pressure.

    A pulse can be felt in the 

    • A.

      Veins

    • B.

      Arteries

    • C.

      Capillaries

    • D.

      Venules

    Correct Answer
    B. Arteries
    Explanation
    Arteries are the correct answer because they are the blood vessels that carry oxygenated blood away from the heart to the rest of the body. The strong contractions of the heart create a pulse, which can be felt in the arteries. Veins carry deoxygenated blood back to the heart, capillaries are tiny blood vessels that connect arteries and veins, and venules are small veins that receive blood from capillaries.

    Tissue fluid contains the following:

    • A.

      Red blood cell

    • B.

      White blood cell

    • C.

      Water

    • D.

      Glucose

    • E.

      Amino acids

    • F.

      Oxygen

    • G.

      Proteins

    Correct Answer(s)
    C. Water
    D. Glucose
    E. Amino acids
    F. Oxygen
    Explanation
    The tissue fluid is a fluid that surrounds the cells in the body and provides them with nutrients and oxygen while removing waste products. It is composed of various substances including water, glucose, amino acids, and oxygen. Water is essential for maintaining the fluidity of tissue fluid and facilitating the transport of other substances. Glucose and amino acids are important energy sources for cells, while oxygen is necessary for cellular respiration. These substances are crucial for the proper functioning of cells and maintaining homeostasis in the body.
