  1. 1Humans - and all other mammals - have a double circulatory system which comprises two separate circuits.
    What does it mean to say the human heart is a 'double pump?
    1. ABlood pumps through the heart twice during a complete journey around the body.
    2. BBlood moves around the body at two different speeds.
    3. CBlood is pumped twice before leaving the heart.
  2. 2The blood in each 'circuit' is interchanged.
    1. AVerdadeiro
    2. BFalso
  3. 3Choose the statements which are correct descriptions of arteries.
    1. AThey carry blood towards the heart.
    2. BThey have very thin walls (only one cell thick) to allow for maximum exchange of substances.
    3. CThey have thick, muscular walls to withstand the high pressure of blood
    4. DThey carry blood away from the heart.
    5. EThey contain valves to prevent blood flowing backwards and 'pooling'.
  4. 4Choose the correct order:

    1. It is pumped to the lungs, via the pulmonary artery where it is oxygenated.
    2. The left side of the heart pumps oxygenated blood from the lungs, through the aorta to the body tissues (excluding the lungs).
    3. Blood returns to the left side of the heart, via the pulmonary vein and is pumped to the body tissues again.
    4. Deoxygenated blood returns from the body tissues to the right side of the heart, via the vena cava.
    1. A2, 4, 1, 3
    2. B3, 2, 4, 1
    3. C1, 2, 3, 4
    4. D2, 1, 4, 3
  5. 5The heart is mainly made from [blank_start]muscle[blank_end]. The left ventricle of the heart has a [blank_start]thicker[blank_end] muscle wall because it needs to pump blood further, and at a higher [blank_start]pressure[blank_end], around the body. The right ventricle is under [blank_start]less[blank_end] pressure as it only needs to pump blood to the [blank_start]lungs[blank_end].

    The heart needs a [blank_start]continuous[blank_end] supply of oxygen and glucose for [blank_start]respiration[blank_end]. The [blank_start]coronary[blank_end] artery is a branch of the aorta which transports [blank_start]blood[blank_end] to the heart muscle itself.

    A [blank_start]blockage[blank_end] in one of the branches of the coronary artery can severely interrupt blood flow and is called a [blank_start]heart attack[blank_end].
    1. Amuscle
    2. Bthicker
    3. Cpressure
    4. Dless
    5. Elungs
    6. Fcontinuous
    7. Grespiration
    8. Hcoronary
    9. Iblood
    10. Jheart attack
    11. Kblockage
  6. 6Which of the four components of blood is being described?
    The liquid part of blood. It transports nutrients (eg glucose), amino acids, antibodies and hormones to tissues that need them. It also transports waste substances: carbon dioxide and water to the lungs, and water and urea to the kidneys.
    1. Aplasma
    2. Bred blood cells
    3. Cwhite blood cells
    4. Dplatelets
  7. 7Which of the four components of blood is being described?
    They transport oxygen, which is bound to haemoglobin.
    1. Ared blood cells
    2. Bwhite blood cells
    3. Cplatelets
    4. Dplasma
  8. 8Which of the four components of blood is being described?
    They are part of the body’s immune system and fight infection.
    1. Ared blood cells
    2. Bwhite blood cells
    3. Cplatlets
    4. Dplasma
  9. 9Which of the four components of blood is being described?
    They stick together when a blood vessel is damaged in order to help form a clot.
    1. Ared blood cells
    2. Bwhite blood cells
    3. Cplasma
    4. Dplatelets
  10. 10Red blood cells' lack of a nucleus is so they are smaller.
    1. AVerdadeiro
    2. BFalso
