- 4. a red protein responsible for transporting oxygen in the blood of vertebrates
- 9. The external factor that causes a change in the state of rest, motion, or direction (or both), or shape of a fixed body
- 10. a hollow part or cavity in an organ
- 13. an artery supplying blood to the heart
- 14. a membranous fold in a hollow organ or tubular structure, such as a blood vessel or the digestive tract, that maintains the flow of the contents in one direction by closing in response to any pressure from reverse flow
- 15. a sudden and sometimes fatal occurrence of coronary thrombosis, typically resulting in the death of part of a heart muscle
- 18. the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended
- 19. the main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone
- 22. refers to the heart, blood vessels and the blood
- 24. the network of vessels through which lymph drains from the tissues into the blood
- 25. an instrument for measuring blood pressure
- 26. each of a number of small swellings in the lymphatic system where lymph is filtered and lymphocytes are formed
- 27. an insoluble protein formed from fibrinogen during the clotting of blood. It forms a fibrous mesh that impedes the flow of blood

- 2. the spreading of something more widely
- 3. the process of transferring the blood of a person into the veins of another
- 5. a small colorless disk-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting
- 6. any of the fine branching blood vessels that form a network between the arterioles and venules
- 7. a disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls
- 8. any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart
- 11. an artificial device for stimulating the heart muscle and regulating its contractions
- 12. A stress or force acting in any direction against resistance
- 16. any of the muscular-walled tubes forming part of the circulation system by which blood is conveyed from the heart to all parts of the body
- 17. a hollow muscular organ that pumps the blood through the circulatory system
- 20. each of the two upper cavities of the heart from which blood is passed to the ventricles
- 21. abnormally high blood pressure
- 23. contain the pigment hemoglobin, which imparts the red color to blood, and transport oxygen and carbon dioxide to and from the tissues
- 24. a colorless fluid containing white blood cells, which bathes the tissues and drains through the lymphatic system into the bloodstream
