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






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






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






4. The period during which the ventricles contract






5. Phloem - cambium - and xylem layers






6. Two lower chambers of the heart -extremely muscular






7. Blood is confined to blood vessel






8. Attracted to the injury site phagocytize antigenic material






9. Where exchange occurs in arthropods






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






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






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






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






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






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






17. Branch into microscopic capillaries






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






19. With the aid of its cofactors calcium and Vitamin K - converts the inactive plasma protein prothrombin to its active form - thrombin






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






21. Composed of nonspecific and specific defense mechanisms






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






23. Carry oxygenated blood from the lungs to the heart






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






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






26. Serve protective functions -aka WBC






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






28. When hemoglobin bind to oxygen






29. 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






30. Responsible for both of these immune mechanisms






31. Excess interstitial fluid






32. Conducts impulse slowly - allowing enough time for atrial contraction and for the ventricles to fill with blood






33. 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






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






35. Actively dividing - undifferentiated cells of a plant






36. 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






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






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






39. 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






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






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






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






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






44. Systole and diastole - which together make a heartbeat






45. Run up and down the stem at the center and contains xylem - phloem - and cambium cells






46. Innervates the heart via the vagus nerve and causes a decrease in the heart rate






47. 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






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






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






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