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






3. Converts fibrinogen (another plasma protein) into fibrin






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






5. Functions to absorb materials through the root hairs and anchor the plant -provide storage for energy reserves






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






7. Engulf and detroy foreign particles






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






9. Phloem - cambium - and xylem layers






10. Physical barier against bacterial invasion






11. Primary organ of transport in the plant






12. Produced by cells under viral attack and diffuse to other cells - where they help prevent the spread of the virus






13. Transport deoxygenated blood from the heart to the lungs






14. Involves cells that combat fungal and viral infection






15. Universal donor since it will not elicit a response from the recipient's immune system because it does not possess any surface antigens






16. Responsible for the proliferationof antibodies after exposure to antigens






17. 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






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






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






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






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






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






23. 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






24. Released by injured cells - which causes blood vessels to dilate - thereby increasing blood flow to the damaged region






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






26. 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






27. Where exchange occurs in arthropods






28. Two lower chambers of the heart -extremely muscular






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






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






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






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






33. 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






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






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






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






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






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






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






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






41. 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






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






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






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






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






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






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






48. Outer layer of xylem that is alive






49. 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)






50. Blood is confined to blood vessel
