Across
- 3. The AV valve that prevents back flow of blood from the right atria to the right ventricle
- 6. refers to the heart relaxing. The pressure it produces in the brachial artery is measured and recorded as the "bottom number" for blood pressure
- 7. Muscular chambers of the heart that pump blood
- 11. The element of an EKG that shows atrial contraction (depolarization)
- 12. This gas diffuses into the blood during the pulmonary circuit.
- 13. refers to the heart contracting. The pressure it produces in the brachial artery is measured and recorded as the "top number" for blood pressure.
- 15. These valves control blood flow to the ventricle from the arteries. S1 is heard when they forcefully snap shut.
- 17. These veins and arteries allow for circulation to the lungs and back to the heart.
- 19. The element of an EKG that shows ventricular contraction (depolarization)
- 20. Chambers of the heart that receive blood
Down
- 1. The AV valve that prevents back flow of blood from the left atria to the left ventricle.
- 2. The superior and inferior vena cava carry oxygen poor blood back to the heart from the ____.
- 4. The category of blood vessel that pumps blood away from the heart, contains a thick layer of smooth muscle and elastic connective tissue.
- 5. The category of blood vessel that is thin enough for nutrient and gas exchange to occur through the walls of the vessel.
- 8. the side of the heart that circulates oxygen rich blood.
- 9. Bundles of electrical cells found in the heart to stimulate muscle contraction
- 10. The category of blood vessel that circulated blood back to the heart. Contains thinner walls and lower blood pressure.
- 14. These valves control blood flood in the major arteries in the heart. They forcefully snap shut, creating S2 of the heart beat.
- 16. The side of the heart that circulates oxygen poor blood.
- 18. artery connected directly to the left ventricle that supplies oxygen rich blood to the body
