  1. Which antecubital vein is considered the least preferred for venipuncture due to its proximity to nerves and arteries?

    Answer: Basilic vein

    The basilic vein is least preferred because it lies close to the brachial artery and the median nerve, increasing the risk of injury.

  2. What term describes the process by which blood flows through capillaries to deliver nutrients and remove waste?

    Answer: Perfusion

    Perfusion refers to the passage of blood through capillary beds to exchange nutrients and waste between blood and tissues.

  3. The aorta is an example of which type of blood vessel?

    Answer: Artery

    The aorta is the largest artery in the body, originating from the left ventricle and distributing oxygenated blood systemically.

  4. Which blood component is responsible for the primary immune response?

    Answer: White blood cells

    White blood cells (leukocytes) are the main cellular components of the immune system, defending the body against infection and disease.

  5. What is the role of platelets in the blood?

    Answer: Initiate clot formation at a wound site

    Platelets (thrombocytes) aggregate at injury sites and release clotting factors to form a platelet plug, initiating hemostasis.

  6. Which plasma protein is essential for blood clot formation?

    Answer: Fibrinogen

    Fibrinogen is converted to fibrin by thrombin during coagulation, forming the mesh that stabilizes a blood clot.
