Across
  1. 3. Referring to blood that has lost its oxygen content, usually returning to the heart from the body's tissues.
  2. 4. The largest artery in the body, which carries oxygen-rich blood from the heart to the rest of the body.
  3. 6. Pertaining to the systemic circulation, which carries oxygen-rich blood from the heart to the body and returns deoxygenated blood back to the heart.
  4. 9. The study of blood flow and the forces involved in the circulation of blood within the cardiovascular system.
  5. 10. A fluid connective tissue that transports oxygen, nutrients, hormones, and waste products throughout the body.
  6. 12. Blood vessels that carry oxygen-rich blood away from the heart to the body's tissues.
  7. 13. The process of adding oxygen to the blood, typically occurring in the lungs when oxygen is exchanged for carbon dioxide.
  8. 17. The continuous movement of blood through the heart and blood vessels, delivering oxygen and nutrients to cells and removing waste products.
  9. 19. Structures within the heart and veins that prevent the backflow of blood, ensuring it flows in one direction.
Down
  1. 1. Pressure The force exerted by circulating blood on the walls of blood vessels, often measured to assess cardiovascular health.
  2. 2. A condition characterized by the hardening and narrowing of arteries due to plaque buildup, increasing the risk of heart disease and stroke.
  3. 5. The formation of a blood clot within a blood vessel, which can obstruct blood flow.
  4. 7. A protein in red blood cells that binds oxygen and carries it from the lungs to the tissues.
  5. 8. Pertaining to the coronary arteries, which supply blood to the heart muscle itself.
  6. 11. Small, thin-walled blood vessels that connect arteries and veins, allowing for the exchange of oxygen, carbon dioxide, nutrients, and waste products between blood and tissues.
  7. 14. Related to the lungs; often refers to the pulmonary circulation, which is the path blood takes from the heart to the lungs and back.
  8. 15. Blood vessels that return deoxygenated blood from the body back to the heart.
  9. 16. A thin layer of cells lining the blood vessels, which helps regulate the passage of substances and maintains blood flow.
  10. 18. A buildup of fatty deposits, cholesterol, and other substances in the arteries that can restrict blood flow.
  11. 19. Relating to blood vessels (arteries, veins, and capillaries) and the system that transports blood throughout the body.
