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 the proliferationof antibodies after exposure to antigens






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






3. Outer layer of xylem that is alive






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






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






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






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






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






9. 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






10. Excess interstitial fluid






11. 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






12. Phloem - cambium - and xylem layers






13. Attracted to the injury site phagocytize antigenic material






14. Two upper chambers of the heart -thin walled






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






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






17. 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






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






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






20. Branches into a series of arteries






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






22. The driving force of the circulatory system






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






24. Primary organ of transport in the plant






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






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






27. Where exchange occurs in arthropods






28. 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






29. Tissue involved in storage of nutrients and plant support






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






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






32. Converts fibrinogen (another plasma protein) into fibrin






33. 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






34. Defined as the total volume of blood the left ventricle pumps out per minute = heart rate (number of BPM) x stroke volume (volume of blood pumped out of the left ventricle per contraction)






35. Responsible for both of these immune mechanisms






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






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






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






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






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






41. Branch into microscopic capillaries






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






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






44. Transport deoxygenated blood from the heart to the lungs






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






46. Systole and diastole - which together make a heartbeat






47. The period during which the ventricles contract






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






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






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