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. The driving force of the circulatory system






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






3. Outer layer of xylem that is alive






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






5. Branches into a series of arteries






6. Two lower chambers of the heart -extremely muscular






7. 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






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






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






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






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






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






13. Involves cells that combat fungal and viral infection






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






15. Systole and diastole - which together make a heartbeat






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






17. 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






18. Where exchange occurs in arthropods






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






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






21. 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






22. Tissue involved in storage of nutrients and plant support






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






24. Where blood flows through in arthropods






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






26. The period during which the ventricles contract






27. When hemoglobin bind to oxygen






28. Responsible for both of these immune mechanisms






29. Fetal red blood cells (which will have the Rh factor) enter maternal circulation during birth which cause the anti-Rh antibodies she produced when sensitized by the first birth may cross the placenta and destroy fetal red blood cells






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






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






32. Phloem - cambium - and xylem layers






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






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






35. Actively dividing - undifferentiated cells of a plant






36. Primary organ of transport in the plant






37. Converts fibrinogen (another plasma protein) into fibrin






38. Cells that are thick walled - often hollow cells located on the inside of the vascular bundle that carry water and minerals up the plant - and their thick walls give the plant its rigid support






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






40. 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)






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






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






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






44. Attracted to the injury site phagocytize antigenic material






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






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






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






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






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






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