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. Responsible for both of these immune mechanisms






2. Fluid left after blood clotting






3. Branch into arterioles






4. Primary organ of transport in the plant






5. Systole and diastole - which together make a heartbeat






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






7. 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






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






9. Involves cells that combat fungal and viral infection






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






11. The production of antibodies during an immune response -can be conferred by vaccination






12. 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






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






14. Branches into a series of arteries






15. The driving force of the circulatory system






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






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






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






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






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






21. An individual is injected witha weakened - inactive - or related form of a particular antigen - which stimulates the immune system to produce specific antibodies against it






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






23. Where blood flows through in arthropods






24. Include arteries - veins - and capilleries






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






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






27. Inappropriate response to certain foods and pollen that cause the body to form antibodies and release histamine






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






29. The period during which the ventricles contract






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






31. Physical barier against bacterial invasion






32. 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)






33. 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






34. Carry oxygenated blood from the lungs to the heart






35. Have body walls that are two cells thick -all cels are direct contact with either the internal or external environments so there is no need for a specialized circulatory system






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






37. Thin walled cells on the outside of the vascular bundle that transport nutrients down the stem -are living and include sieve tube cells and companion cells






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






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






40. Lying between the phloem and xylem - is a type of meristem called lateral meristem that provides for lateral growth of the stem by adding to the phloem or xylem






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






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






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






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






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






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






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






48. Supply plant cells with nutrients and remove waste products






49. Blood is confined to blood vessel






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