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. Transport deoxygenated blood from the heart to the lungs






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






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






4. Include arteries - veins - and capilleries






5. The driving force of the circulatory system






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






7. 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






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






9. Responsible for both of these immune mechanisms






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






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






12. 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






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






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






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






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






17. Serve protective functions -aka WBC






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






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






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






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






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






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






24. Innervates the heart via the vagus nerve and causes a decrease in the heart rate






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






26. 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






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






28. 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






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






30. When hemoglobin bind to oxygen






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






32. Engulf and detroy foreign particles






33. 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






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






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






36. Attracted to the injury site phagocytize antigenic material






37. Blood is confined to blood vessel






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






39. Where blood flows through in arthropods






40. Phloem - cambium - and xylem layers






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






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






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






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






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






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






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






48. Systole and diastole - which together make a heartbeat






49. 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)






50. Fluid left after blood clotting
