Across
2. The liquid produced by the kidneys containing the metabolic waste product urea along with excess water
and salts from the body.
3. Chemical which can be used as artificial blood.
4. The liquid which is pumped around the body by the heart. It contains blood cells, dissolved food, oxygen,
waste products, mineral ions, hormones and other substances needed in the body or needing to be removed
from the body.
6. Blood cell which contains the red pigment haemoglobin. It is biconcave discs in shape and gives the blood
its red colour.
7. A coloured molecule.
9. Blood vessel which carries blood away from the heart. It usually carries oxygenated blood and it has a
pulse.
10. Lacking in oxygen.
13. The living transport tissue in plants which carries sugars around the plant.
15. The separate circulation of the blood from the heart to the lungs and then back again to the heart and on
to the body.
18. The transfer of blood from one person to another.
19. The non-living transport tissues in plants, which transports water and minerals around the plant.
21. The small upper chambers of the heart.
22. An artery which carries oxygenated blood to the muscle of the heart.
23. The main artery leaving the left ventricle carrying oxygenated blood to the body.
24. Blood cell which involved in the immune system of the body, engulfing bacteria, making antibodies and
making antitoxins.
29. Fragment of cell in the blood which is vital for the clotting mechanisms to work.
30. A metal mesh placed in the artery which is used to open up the blood vessel by the inflation of a tiny
balloon.
31. Blood vessel which carries blood to the heart. It usually carries deoxygenated blood and has valves to
prevent the backflow of blood.
32. The smallest blood vessels which run between individual cells. They have a wall that is only one cell thick.

1. The system by which blood is pumped around the body.
5. A tube which carries blood around the body, i.e. veins, arteries and capillaries.
8. Containing oxygen.
11. Structure which prevents the backflow of liquid, e.g. the valves of the heart or veins.
12. The person who gives material from their body to another person who needs healthy tissues or organs,
e.g. blood, kidneys. Donors may be alive or dead.
13. The large blood vessel bringing oxygenated blood into the left atrium of the heart from the lungs.
14. The large blood vessel taking deoxygenated blood from the right ventricle of the heart to the lungs.
16. The molecule formed when haemoglobin binds to oxygen molecules.
17. The large vein going into the right atrium of the heart carrying deoxygenated blood from the body.
20. The waste produce formed by the breakdown of excess amino acids in the liver.
25. The red pigment which carried oxygen around the body.
26. A system for transporting substances around a multicellular organism.
27. The shape of red blood cells – a disc which is dimpled inwards on both sides.
28. The clear, yellow liquid part of the blood which carries dissolved substances and blood cells around the
body.
31. The large chambers at the bottom of the heart.
