- 3. Largest artery in the body
- 4. Arteries supplying blood to the thighs
- 7. Heart valve between left atrium & ventricle
- 8. The thickness of a fluid

- 23. Nerve fibers that carry impulses to distant regions of the ventricular myocardium
- 24. Blood vessels that carry blood toward the heart
- 26. Maximum arterial pressure when the heart contracts
