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. When hemoglobin bind to oxygen






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






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






4. Responsible for the proliferationof antibodies after exposure to antigens






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






6. The period during which the ventricles contract






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






8. Physical barier against bacterial invasion






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






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






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






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






13. Include arteries - veins - and capilleries






14. Attracted to the injury site phagocytize antigenic material






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






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






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. Branch into arterioles






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






20. Outer layer of xylem that is alive






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






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






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






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






25. 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)






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






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






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






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






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. 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






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






33. 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






34. Responsible for both of these immune mechanisms






35. Composed of nonspecific and specific defense mechanisms






36. Branch into microscopic capillaries






37. Pumps oxygenated blood into systemic circulation (throughout the body)






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






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






40. 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






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






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






43. Two lower chambers of the heart -extremely muscular






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






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






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






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






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






49. Involves cells that combat fungal and viral infection






50. Excess interstitial fluid
