Across
- 1. are at the apex of the heart.
- 2. is when platelets stick to each other and the damaged area, and release a mixture of chemicals.
- 6. involved in allergic reactions.
- 7. transmit the electrical signal down the septum.
- 9. feed the heart muscle tissue itself with oxygen and nutrients.
- 11. pumps blood to the right ventricle.
- 14. prevents back flow of blood into the left atrium.
- 16. pumps blood to the body.
- 17. semilunar valve prevents back flow of blood back into the right ventricle.
- 18. attack and destroy invading pathogens.
- 24. pumps blood to the lungs.
- 25. carry oxygen and carbon dioxide.
- 26. increase allergic and inflammatory responses.
- 27. is the main artery in the body.
- 28. is a hairpin loop in the aorta that wraps around the pulmonary veins and heads downwards.
- 30. prevents back flow of blood back into the left ventricle and has three flaps.
- 31. are immune molecules that poke holes in rbc’s causing them to burst and release hemoglobin.
- 32. is where all the veins from the head merge together.
Down
- 1. help the blood to clot at wounds.
- 2. carry oxygen poor blood back to the lungs.
- 3. prevents back flow of blood back to the right atrium.
- 4. carry oxygen rich blood to the heart from the lungs.
- 5. can consume bacteria by phagocytosis and are granular.
- 8. is an involuntary contraction of damaged arteries or arterioles.
- 10. is located in the inferior inner surface of the right atria.
- 12. develop antibodies and attack bacteria.
- 13. is where all the veins from the lower merge together.
- 15. is a series of events that cause the blood to thicken into a gel-like consistency.
- 19. pumps blood from the lungs into the left ventricle.
- 20. is the part of the aorta that heads down.
- 21. sends a signal for the rest of the heart when to contract. \
- 22. is a missing clotting factor that causes the blood to not clot properly.
- 23. can consume bacteria by phagocytosis and are agranular.
- 29. can bind readily to oxygen and carbon dioxide.
