Across
- 2. Form at the congregation of many capillaries. Eventually, many congregate to form a vein.
- 5. Organ that pumps blood through the circulatory system.
- 6. Yelowish liquid component of blood that holds blood cells in suspension. Makes up ~55% of out blood volume.
- 8. Colorless fluid that contains white blood cells and bathes the tissues.
- 9. 2 upper cavities of the heart which receive blood from veins.
- 11. Blood vessels which carry blood away from the heart at high pressure. Thick and flexible.
- 14. Circulation that pumps blood to and from the lungs
- 15. Branch from the arteries at the tissues the artery was heading to. Can contract, controlling blood flow.
- 17. Red blood cells
- 18. Quivering or irregular heartbeat that can lead to blood clots and heart failure.
- 19. Muscular tissue of the heart
- 20. Circulation that pumps blood to and from the rest of the body (Except the lungs)
Down
- 1. Body fluid that delivers nutrients and oxygen to cells and transports metabolic waste products away from cells.
- 2. 2 large chambers in the heart that receive blood from the atrium, and pump it out through arteries.
- 3. Valves which that prevent the flow of blood back into the heart. Found in the heart and major arteries.
- 4. Fine branching blood vessels that form a network between veins and arteries. Deliver blood c=to individual cells.
- 7. Valves which connect the atriums to the ventricles, allowing the control of blood flow between them.
- 10. Blood vessels that carry blood to the heart, at low speeds and pressures. Thinner than arteries.
- 12. Tissue that forms the intermost layer of blood vessels.
- 13. Type of cell capable of engulfing and absorbing bacteria and other small cells/particles.
- 16. Muscular wall that completely divides the heart into 2 sections
