Across
- 2. substance that is pumped by the heart through veins and arteries; delivers nutrients and oxygen to body cells and removes waste products like CO2
- 4. used to describe veins/arteries leading to lungs
- 6. membrane that separates heart from other bodily structures
- 12. when muscles cells squeeze together to get smaller and produce movement; in the heart this is called systole
- 13. largest artery in the body, oxygenated blood from heart travels through it to the rest of the bpdy
- 14. structure that can open/close to let blood through; prevent backflow of blood.
- 16. walls that separate heart chambers; prevent mixing of blood
- 18. valve that oxygenates blood from left ventricle travels through to get to the aorta
- 20. type of circulation that supplies blood for the heart itself to FUNCTION, not pump around the body
- 21. pump blood out of the heart
Down
- 1. circuit that transports blood from heart to lungs & back to oxygenate blood
- 3. circuit that transports blood from heart to body and back to oxygenate body tissues
- 5. inferior tip of heart
- 7. heart is a cardiac _______
- 8. a.k.a left atrioventricular valve or bicuspid valve, separates left atfrium from left ventricle
- 9. act as holding chambers for blood; pump into ventricles
- 10. vessels that return deoxygenated blood to the heart; inferior / superior ____ ____
- 11. number of chambers in the heart
- 15. measured in bpm (beats per minute), the number of contractions that the heart undergoes per minute; cardiac output divided by stroke volume equals this
- 17. a.k.a right atrioventricular valve,separate right atrium from right ventricle
- 19. in the lungs, carbon dioxide diffuses out of blood and this diffuses in.
