- 11. valves that prevent the backflow of blood from the ventricles to the atria when ventricular pressure exceeds atrial pressure
- 12. blood vessels that carry blood from capillaries back to the heart
- 14. hollow tubes through which water is transported in a plant
- 15. blood vessels that carry blood away from the heart and into arterioles
- 16. relaxation of the heart
- 17. major blood vessels connected to the left ventricle that carries oxygenated blood to the entire body (except the lungs)
- 18. protein molecules with a quaternary structure adapted to efficiently load and unload oxygen in certain conditions
Down

- 4. word to describe the major blood vessels that carry blood to and from the lungs
- 5. watery liquid like blood plasma that supplies substances, such as glucose, oxygen and amino acids, to tissues
- 6. the evaporation of water off the surface of leaves
- 7. thin-walled, elastic chamber of the heart that stretches as it collects blood
- 9. the central cavity of blood vessels through which blood flows
- 10. graph of the relationship between the saturation of haemoglobin with oxygen and the partial pressure of oxygen, different for every animal
