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






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






3. 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






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






5. Converts fibrinogen (another plasma protein) into fibrin






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






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






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






9. Modifies the rate of heart contraction






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






11. Involves cells that combat fungal and viral infection






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






13. 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






14. Engulf and detroy foreign particles






15. Responsible for the proliferationof antibodies after exposure to antigens






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






17. Specialized of the root epidermis with thin-walled projections increase the surface area for absorption of water and minerals from the soil






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






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






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






21. 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)






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






23. Outer layer of xylem that is alive






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






25. 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






26. 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






27. Blood is confined to blood vessel






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






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






30. 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






31. Actively dividing - undifferentiated cells of a plant






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






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






34. Have body walls that are two cells thick -all cels are direct contact with either the internal or external environments so there is no need for a specialized circulatory system






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






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






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






38. Systole and diastole - which together make a heartbeat






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






40. Transport deoxygenated blood from the heart to the lungs






41. 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






42. Primary organ of transport in the plant






43. Attracted to the injury site phagocytize antigenic material






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






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






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






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






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






49. Include arteries - veins - and capilleries






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