PCAT Biology Vascular Systems In Animals And Plants

Subjects : pcat, biology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The period during which the ventricles contract






2. Leukocytes that phagocytize foreign matter and organisms such as bacteria






3. Released by injured cells - which causes blood vessels to dilate - thereby increasing blood flow to the damaged region






4. Skin - mucous-coated epithelia - macrophages - inflammatory - interferons






5. Valve on the right side of the heart has three cusps






6. Modifies the rate of heart contraction






7. Include arteries - veins - and capilleries






8. Water entering the root hairs exerts a pressure that pushes water up the stem






9. Where exchange occurs in arthropods






10. A small mass of specialized tissue located in the wall of the right atrium regulates/originates an ordinary cardiac contraction -spreads impulses through both atria - stimulating them to contract simultaneously






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






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






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






14. AKA immunoglobulins (Igs) -defense mechanism that are complex proteins that recognize and bind to specific antigens and trigger the immune system to remove them -either attract other cells to phagocytize the antigen or cause the antigens to clump tog






15. Blood is confined to blood vessel






16. Composed of nonspecific and specific defense mechanisms






17. When hemoglobin bind to oxygen






18. Carry oxygenated blood from the lungs to the heart






19. Actively dividing - undifferentiated cells of a plant






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






21. Produced by cells under viral attack and diffuse to other cells - where they help prevent the spread of the virus






22. 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






23. Pumps oxygenated blood into systemic circulation (throughout the body)






24. Where blood flows through in arthropods






25. Involves the transfer of antibodies produced by another individual or organism -acquired either passively or by injection






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






27. Responsible for the proliferationof antibodies after exposure to antigens






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






29. Thick-walled - muscular - elastic vessels that transport oxygenated blood away from the heart






30. Responsible for both of these immune mechanisms






31. Used to lower the immune response to transplants and decrease the likelihood of rejection






32. Exchange of gases - nutrients - and cellular waste products occurs via diffusion across this






33. Functions to absorb materials through the root hairs and anchor the plant -provide storage for energy reserves






34. Leukocytes that migrate from the blood to tissue - where they mature into stationary cells






35. Cell-surface proteins that are macromolecules that are foreign to the host organism and trigger an immune response ex: ABO group and the Rh factor






36. Attracted to the injury site phagocytize antigenic material






37. In annelids - five pairs of vessels that connect the dorsal vessel to the ventral vessel and function as additional pumps






38. Branch into arterioles






39. Epidermis (outer-bark) - cortex - phloem - cambium - xylem - and pith






40. Relatively thinly walled - inelastic vessels that conduct deoxygenated blood toward the heart






41. Lined in passages - which filter and trap foreign particles






42. Responsible for generating the force that propels systematic circulation and pumps against a higher resistance






43. Involves cells that combat fungal and viral infection






44. Converts fibrinogen (another plasma protein) into fibrin






45. Cells that are thick walled - often hollow cells located on the inside of the vascular bundle that carry water and minerals up the plant - and their thick walls give the plant its rigid support






46. Valve on the left side of the heart that has two cusps






47. Blood transports nutrients and O2 to tissue and wastes and CO2 from tissue -transport of gases - transport of nutrients and wste - and clotting






48. Severe anemia for the fetus caused by Rh+ fetus






49. Leukocytes involved in immune response and the production of antibodies (B cells) or cytolysis of infected cells (T cells)






50. Excess interstitial fluid
