Down
- 1. state of balance or equilibrium between all systems and processes within the body
- 2. to all of the living tissues of the body and carry away carbon dioxide
- 4. eat microorganisms and other substances
- 5. considered to be present when a person’s systolic blood pressure is consistently 140mmHg or greater, and/or their diastolic blood pressure is consistently 90mmHg or greater, known as high blood pressure
- 6. protect the body against invading organisms and remove dead cells and other waste from the body
- 8. Potentials originate in the SA node and travel across the walls of the atrium to the AV node
- 10. smaller, thinner tubes of arteries which become fine branches
- 11. fatty material on the inner lining of the arteries causing them to narrow and be less flexible
- 13. Node located in the walls of the right atrium
- 15. regulates blood flow between the right atrium and right ventricle
- 16. strong elastic vessels designed to carry blood away from the heart at a high pressure
- 17. controls blood flow from the right ventricle into the pulmonary arteries, which carry blood to your lungs to pick up oxygen
