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. 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






2. Primary organ of transport in the plant






3. 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






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






5. Outer layer of xylem that is alive






6. Branch into microscopic capillaries






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






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






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






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






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






12. Fraction of the blood containing a wide variety of antibodies - that can be used to confer temporary protection against hepatitis and other diseases by passive immunity






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






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






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






16. Fluid left after blood clotting






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






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






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






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






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






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






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






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






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






26. When hemoglobin bind to oxygen






27. 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






28. Supply plant cells with nutrients and remove waste products






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






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






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






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






33. Attracted to the injury site phagocytize antigenic material






34. The period during which the ventricles contract






35. 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






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






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






38. Two layers thick and are the actively dividing - undifferentiated cells that give rise to xylem and phloem cell layers; as they divide - the cells near the phloem differentiate into phloem cells - and the cells near the xylem differentiate into xylem






39. Liquid portion of the blood -aqueous mixture of nutrients - salts - respiratory gases - wastes - hormones - and blood proteins -components are erythrocytes - leukocytes - and platelets






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






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






43. Branches into a series of arteries






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






45. Converts fibrinogen (another plasma protein) into fibrin






46. Include arteries - veins - and capilleries






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






48. 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






49. Where blood flows through in arthropods






50. Excess interstitial fluid
