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






2. Any liquid in a thin tube will rise becaUse of the surface tension of the liquid and interactions between the liquid and the tube






3. Actively dividing - undifferentiated cells of a plant






4. Heterotrophic cells that generally consume other cells or food particles -movement of gases and nutrients is a ccomplished by simple diffusion within the cell






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






6. Attracted to the injury site phagocytize antigenic material






7. Modifies the rate of heart contraction






8. Involves cells that combat fungal and viral infection






9. Primary organ of transport in the plant






10. Have three cusps and are located between the left ventricle and the aorta and between the right ventricle and the pumonary artery (the pulmonic valve)






11. Responsible for the proliferationof antibodies after exposure to antigens






12. Pumps deoxygenated blood into pulmonary circulation (toward the lungs)






13. Exerts hormonal control via epinepherine (adrenaline) secretion - which causes an increase in heart rate






14. Include arteries - veins - and capilleries






15. Carry oxygenated blood from the lungs to the heart






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






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






18. Composed of muscular - four-chambered heart - a network of blood vessels - and the blood itself






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






20. Where exchange occurs in arthropods






21. (earthworm) uses a closed circulatory system to deliver materials to cells that are not in direct contact with the external environment






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






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






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






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






26. Serve protective functions -aka WBC






27. Fluid left after blood clotting






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






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






30. Outer layer of xylem that is alive






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






32. Responsible for both of these immune mechanisms






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






34. Universal donor since it will not elicit a response from the recipient's immune system because it does not possess any surface antigens






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






36. When hemoglobin bind to oxygen






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






38. Engulf and detroy foreign particles






39. The driving force of the circulatory system






40. Branch into arterioles






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






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






43. Prevent extensive blood loss while the damaged vessel heals itself






44. Blood is confined to blood vessel






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






46. Cell fragments that lack nuclei and are involved in clot formation -involved in injury repair






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






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






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






50. Secrete sweat - which contains an enzyme that attacks bacterial cell walls
