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. Leukocytes that phagocytize foreign matter and organisms such as bacteria






2. 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






3. When hemoglobin bind to oxygen






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






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






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






7. 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






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






9. Transport deoxygenated blood from the heart to the lungs






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






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






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






13. Modifies the rate of heart contraction






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






15. 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






16. Attracted to the injury site phagocytize antigenic material






17. Where blood flows through in arthropods






18. 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






19. 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






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






21. The period during which the ventricles contract






22. Carry oxygenated blood from the lungs to the heart






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






24. Excess interstitial fluid






25. Where exchange occurs in arthropods






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






27. 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






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






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






30. Primary organ of transport in the plant






31. Branch into arterioles






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






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






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






35. Physical barier against bacterial invasion






36. Engulf and detroy foreign particles






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






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






39. 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






40. Inappropriate response to certain foods and pollen that cause the body to form antibodies and release histamine






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






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






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






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






45. Branch into microscopic capillaries






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






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






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






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






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