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






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






3. Branches into a series of arteries






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






5. 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






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






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






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






9. 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)






10. Engulf and detroy foreign particles






11. The driving force of the circulatory system






12. AKA immunoglobulins (Igs) -defense mechanism that are complex proteins that recognize and bind to specific antigens and trigger the immune system to remove them -either attract other cells to phagocytize the antigen or cause the antigens to clump tog






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






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






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






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






17. Two lower chambers of the heart -extremely muscular






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






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






20. 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






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






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






23. Where exchange occurs in arthropods






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






25. Carry oxygenated blood from the lungs to the heart






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






27. Responsible for both of these immune mechanisms






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






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






30. When hemoglobin bind to oxygen






31. Physical barier against bacterial invasion






32. Tissue involved in storage of nutrients and plant support






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






34. Excess interstitial fluid






35. Phloem - cambium - and xylem layers






36. Composed of nonspecific and specific defense mechanisms






37. 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






38. Involves cells that combat fungal and viral infection






39. Modifies the rate of heart contraction






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






41. 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






42. 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






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






44. Actively dividing - undifferentiated cells of a plant






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






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






47. Two upper chambers of the heart -thin walled






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






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






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