Across
- 4. what delivers oxygenated blood from the lungs to the left side of the heart
- 5. what colour is oxyhaemoglobin
- 6. what system transports oxygenated blood from the heart to the body to deliver o2 and then back to the heart
- 10. what valve separates the atrium and ventricle, keeping the blood flowing in the right direction - it is attached to the ventricular walls with tendons(dont strech)
- 13. what do the ventricles do that produces the pressure that transports the blood around the body
- 15. what delivers deoxygenated blood to the right side of the heart
- 16. what muscle is the heart made out of that can contract and relax repeatedly
- 17. what separates the left and right side of the heart
- 18. what pumps oxygenated blood from the heart to the rest of the body
- 19. what valve separates the aorta/pulmonary artery from the ventricles
- 20. the system used by humans for blood to be pumped through the body, it travels trough the heart twice in one cycle
Down
- 1. what pumps deoxygenated blood from the heart to the lungs
- 2. what colours is haemoglobin
- 3. what is the lower chamber called
- 7. these provide the heart with blood(own supply)they break away from the aorta and snake around the cardiac muscle
- 8. which system transports deoxygenated blood to the lungs to take up o2 and then back to the heart
- 9. the system of tubes that blood flows through, movement through these tubes is caused by a pressure change from the contraction of the heart
- 11. what is the upper chamber called
- 12. there are 2 pumps in the heart each are made up of 2 what
- 14. are the walls of the atrium thicker or thinner than the ventricles
- 21. what ventricle wall is thicker, right(pumps to lungs) or left(pumps to rest of the body)
