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






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






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






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






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






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






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






8. Carry oxygenated blood from the lungs to the heart






9. Modifies the rate of heart contraction






10. Involves cells that combat fungal and viral infection






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






12. The driving force of the circulatory system






13. Primary organ of transport in the plant






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






15. Responsible for both of these immune mechanisms






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






17. Tissue involved in storage of nutrients and plant support






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






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






20. Two upper chambers of the heart -thin walled






21. Attracted to the injury site phagocytize antigenic material






22. Systole and diastole - which together make a heartbeat






23. 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)






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






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






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






27. Blood is confined to blood vessel






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






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






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






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






32. Phloem - cambium - and xylem layers






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






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






35. Converts fibrinogen (another plasma protein) into fibrin






36. When hemoglobin bind to oxygen






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






38. Excess interstitial fluid






39. Branch into arterioles






40. Innervates the heart via the cervical and upper thoracic ganglia and causes an increase in the ehart rate






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






42. 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






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






44. The period during which the ventricles contract






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






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






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






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






49. 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






50. Leukocytes that phagocytize foreign matter and organisms such as bacteria
