- 5. - any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body
- 7. Valve- lies between the two chambers on the right side of your heart consists of three flaps of tissue called leaflets.
- 8. make or become smaller or fewer in size, amount, intensity, or degree.
- 10. The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax)
- 11. Dioxide- a chemical compound composed of one carbon and two oxygen atoms
- 14. any of a number of disorders in which there is an intense localized pain
- 15. become or make greater in size, amount, intensity, or degree.
- 16. high or raised blood pressure, is a condition in which the blood vessels have persistently raised pressure
- 17. each of the two upper cavities of the heart from which blood is passed to the ventricles. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein
- 19. Artery- the network of blood vessels that branch off the aorta to supply the heart muscle with oxygen-rich blood.
- 21. a small branch of an artery leading into capillaries.
- 22. 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.
Down
- 1. Artery- the artery carrying blood from the right ventricle of the heart to the lungs for oxygenation.
- 2. Node- a small body of specialized muscle fibers, located in the right atrium of the heart, whose activity is responsible for initiating the heartbeat.
- 3. a hollow part or cavity in an organ
- 4. any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart
- 6. done without will or conscious control
- 8. remove oxygen from
- 9. any of the fine branching blood vessels that form a network between the arterioles and venules
- 12. supplied, treated, or enriched with oxygen
- 13. a very small vein, especially one collecting blood from the capillaries.
- 18. 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.
- 20. Cava- a large vein carrying deoxygenated blood into the heart
