Anatomy Of Blood Vessels - Quiz


Questions and Answers
  • 1. 

    Blood vessels are tubes that carry blood _____ from the heart toward the _____ of the body and then return the blood to the heart.

    Explanation
    Blood vessels are the tubes that transport blood away from the heart towards the tissues of the body. Once the blood reaches the tissues, it delivers oxygen and nutrients while removing waste products. After this exchange, the blood is then returned back to the heart through the blood vessels to be pumped again.

  • 2. 

    Arteries carry blood _____ from the heart.

    Explanation
    Arteries carry blood away from the heart.

    Rate this question:

  • 3. 

    Arteries branch extensively and eventually give rise to _______.

    Explanation
    Arteries are blood vessels that carry oxygenated blood away from the heart to various parts of the body. They branch extensively, forming smaller vessels called arterioles. Arterioles are responsible for regulating blood flow and distributing oxygenated blood to specific tissues and organs. Therefore, it is logical to conclude that arteries give rise to arterioles as they continue to divide and branch out.

  • 4. 

    Arterioles branch into ______.

    Explanation
    Arterioles, which are small blood vessels, branch into capillaries. Capillaries are the smallest blood vessels in the body and they connect arterioles to venules. They have thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. This branching network of capillaries ensures that every cell in the body is supplied with oxygen and nutrients while waste products are removed.

  • 5. 

    Capillaries merge to form ______.

    Explanation
    Capillaries are tiny blood vessels that connect arterioles (small arteries) to venules (small veins). They are responsible for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. As capillaries merge, they combine to form venules, which then further merge to form larger veins. This allows for the return of deoxygenated blood back to the heart. Therefore, the correct answer is venules.

    Rate this question:

  • 6. 

    Venules merge to form ______.

    Explanation
    Venules are small blood vessels that collect blood from capillaries and merge together to form veins. Veins are larger blood vessels that carry deoxygenated blood back to the heart. Therefore, the correct answer is veins.

    Rate this question:

  • 7. 

    Veins merge with each other to form progressively larger veins which carry blood back to the ______.

    Explanation
    Veins play a crucial role in the circulatory system by carrying deoxygenated blood back to the heart. As blood flows through smaller veins, they gradually merge and form larger veins. These larger veins continue to merge until they eventually reach the heart. This process allows for efficient blood flow and ensures that oxygen-depleted blood is returned to the heart where it can be pumped to the lungs for oxygenation.

    Rate this question:

  • 8. 

    Larger blood vessels are served by their own blood vessels called ______.

    Explanation
    The correct answer is "vasa vasorum". Vasa vasorum refers to the network of blood vessels that supply larger blood vessels, such as arteries and veins. These blood vessels help to nourish the walls of the larger blood vessels, ensuring their proper functioning and health.

    Rate this question:

  • 9. 

    _______ refers to the growth of new blood vessels.

    Explanation
    Angiogenesis is the process of forming new blood vessels from pre-existing ones. It plays a crucial role in various physiological processes such as wound healing and development of the circulatory system. Angiogenesis is also involved in pathological conditions like cancer, where tumors require a blood supply to grow and spread. Therefore, angiogenesis refers to the growth of new blood vessels.
