- 11. This is a protein that carries oxygen and carbon dioxide, this molecule has the ability to transport up to 4 oxygen molecules.
- 12. One of the cardiovascular systems functions is to remove this by bringing carbon dioxide away from cells.

- 14. In 1 of the main phases, the heart contracts and does this with the blood.
Down
- 1. This process moves materials in and out of cells. It also carries oxygen to cells and carbon dioxide in to be removed.
- 2. Veins contain these so that if blood is flowing back to the heart, and there is a little amount of force, the blood wont flow backwards. These will close if this does happen.
- 3. Thick, elastic walled vessels that carry blood away from the heart. Blood is forced through them from the heart, and must be able to withstand pressure from the heart.
- 5. These donut shaped cells carry oxygen and carbon dioxide, they also contain hemoglobin.
- 7. The main artery that carries blood from the heart to the body and is located towards the top of the heart.
- 9. In loop 2, Blood returns to the heart through this part of the heart, and then into the right atrium.
