    • What are the functions of arteries, veins, and capillaries?
      Transport blood throughout the body
    • Which arteries and veins must you name according to the AQA specification?
      The arteries and veins serving the kidneys
    • What type of circulatory system do mammals have?
      A double circulatory system
    • What is the blood like in the right side of the heart?
      Deoxygenated
    • What is the blood like in the left side of the heart?
      Oxygenated
    • How is the heart diagram oriented in the video?
      The right side is shown on the left
    • Which organs are named in the diagram?
      The kidneys
    • What happens to blood pressure in arteries during heart contractions?
      It increases with each contraction
    • What is the term for the pressure of blood in arteries?
      The pulse
    • How does blood move in arteries between heart contractions?
      It continually moves forward
    • What is the only artery that carries deoxygenated blood?
      The pulmonary artery
    • What is the name of the large artery that carries oxygenated blood to the body?
      The aorta
    • How are individual arteries named?
      Based on the organ they supply
    • What arteries supply the kidneys?
      The renal arteries
    • What are arterioles?
      Blood vessels that lead to organs
    • What are capillaries responsible for?
      Gas exchange between blood and cells
    • What diffuses from blood to body cells in capillaries?
      Oxygen
    • What diffuses from body cells back into the blood?
      Carbon dioxide
    • What happens to blood pressure after passing through capillaries?
      It is much lower
    • What are venules?
      Larger blood vessels that collect blood
    • What do veins carry towards the heart?
      Oxygenated blood from organs
    • What are the veins from the kidneys called?
      The renal veins
    • What is the blood pressure like in veins?
      Relatively low
    • How do veins differ from arteries in terms of blood flow?
      Blood in veins is not surging in pulses
    • What is the name of the large vein that returns deoxygenated blood to the heart?
      The vena cava
    • What is the exception regarding blood flow from the lungs?
      It travels in the pulmonary vein
    • What type of blood is found in the pulmonary vein?
      Oxygenated blood
    • What is the relationship between the structure and function of blood vessels?
      • Structure depends on function
      • Arteries: thick walls for high pressure
      • Veins: thinner walls for low pressure
      • Capillaries: thin walls for gas exchange
