25 Questions

1. Universal recipient as it has neither anti-A nor anti-B antibodies

2. Smallest diameter of all three types of vessels; red blood cells must often travel through them single file

3. Blood is confined to blood vessel

4. Tissue involved in storage of nutrients and plant support

5. The period of cardiac muscle relaxation during which blood drains into all four chambers

6. Systole and diastole - which together make a heartbeat

7. Located between the atria and ventricles on both sides of the heart - prevent backflow of blood into the atria

8. Located at the tips of roots and stems where division leads to increase in length

9. Cardiac muscle contracts rhythmically without stimulation from the nervous system - producing impulses that spread through its internal conducting system

10. Have open circulatory systems in which blood (interstitial fluid) is in direct contact with the body tissues -blood is circulated primarily by body movements

11. Converge into venules and eventually into veins - leading deoxygenated blood back toward the heart

12. Coat the damaged area and trap blood cells to form a clot

13. Involves the production of antibodies and cell-mediated immunity

14. Responsible for the proliferationof antibodies after exposure to antigens

15. Attracted to the injury site phagocytize antigenic material

16. Branch into microscopic capillaries

17. Physical barier against bacterial invasion

18. Another antigen that may be present on the surface of red blood cells

19. Include arteries - veins - and capilleries

20. Branches into a series of arteries

21. Phloem - cambium - and xylem layers

22. Secondary circulatory system distinct from the cardiovascular circulation - =vessels transport lymph to the cardiovascular system - thereby keeping fluid levels in the body constant

23. Composed of nonspecific and specific defense mechanisms

24. Swellins along lyph vessels containing phagocytic cells that filter the lymph - removing and destroying foreign particles and pathogens

25. When platelets come into contact with the exposed collagen of a damaged vessel - they release a chemical chemical that causes neighboring platelets to adherer to one another
