Across
- 4. Upper left division of the heart that retains oxygenated blood from lungs and pumps it to the left ventricle.
- 5. Contraction of heart’s ventricles that usually lasts from 0.3-0.4 seconds.
- 8. Type of atrioventricular valve that divides the right atrium and ventricle, providing blood to the ventricle from the atrium while opened.
- 9. Right and left arteries of the heart in charge of supplying of oxygen and nutrients the heart muscle during coronary circulation.
- 11. Largest vein in the body that transports deoxygenated blood from lower body parts to the heart.
- 12. Lower right division of the heart that collects deoxygenated blood from the right atrium.
- 13. Upper right division of the heart that pumps deoxygenated blood to the right ventricle.
- 14. 4 veins distributed in pairs to each lung that supply oxygenated blood from lungs to the left ventricle during pulmonary circulation.
- 15. Type of atrioventricular valve that closes to fill the left atrium with oxygenated blood, and opens to allow blood-entrance to the left ventricle.
Down
- 1. pulse Rhythmic dilation of an artery, that is provoked when the aortic valve opens and closes.
- 2. Principal artery in our body, cane-shaped, that during systemic circulation carries blood from the heart to other parts of the body.
- 3. Lower left division of the heart considered as the main pumping chamber.
- 6. semilunar valve Specific and semilunar valve that warrants the entrance of blood from the heart to the body.
- 7. Arteries located in the lungs divided into right and left that deliver deoxygenated blood to each lung.
- 10. Specialized structure/bundle that generates electrical impulses for contractions.
