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






2. Actively dividing - undifferentiated cells of a plant






3. Responsible for both of these immune mechanisms






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






5. Phagocytic cells that filter the lymph - removing and destroying foreign particles and pathogens






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






7. 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






8. Innervates the heart via the cervical and upper thoracic ganglia and causes an increase in the ehart rate






9. Outer layer of xylem that is alive






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






11. Modifies the rate of heart contraction






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






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






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






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






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






17. 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






18. Fluid left after blood clotting






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






20. Functions as the main heart by coordinated contractions in annelids






21. 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






22. Two lower chambers of the heart -extremely muscular






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






24. Oxygen carrying components of blood -formed from stem cells in the bone marrow where they lose their nuclei - mitochodnria - and membranous organelles






25. Composed of nonspecific and specific defense mechanisms






26. Carries impuls of AV node which branches into the right and left bundle branches - and through the Purkinje fibers in the walls of ventircles - generating a strong contraction






27. As water evaporates from the leaves of plants - a vacuum is created pulls water up the stem






28. Branch into arterioles






29. Specialized of the root epidermis with thin-walled projections increase the surface area for absorption of water and minerals from the soil






30. Blood is confined to blood vessel






31. Converts fibrinogen (another plasma protein) into fibrin






32. Systole and diastole - which together make a heartbeat






33. Branches into a series of arteries






34. Tissue involved in storage of nutrients and plant support






35. Fetal red blood cells (which will have the Rh factor) enter maternal circulation during birth which cause the anti-Rh antibodies she produced when sensitized by the first birth may cross the placenta and destroy fetal red blood cells






36. Carry oxygenated blood from the lungs to the heart






37. Primary organ of transport in the plant






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






39. Branch into microscopic capillaries






40. Physical barier against bacterial invasion






41. Include arteries - veins - and capilleries






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






43. Engulf and detroy foreign particles






44. Initiated by the body in response to physical damage and often accompanied by fever






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






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






47. When hemoglobin bind to oxygen






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






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






50. Serve protective functions -aka WBC
