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. Lined in passages - which filter and trap foreign particles






3. 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






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






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






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






7. Primary organ of transport in the plant






8. Transport deoxygenated blood from the heart to the lungs






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






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






11. Responsible for the proliferationof antibodies after exposure to antigens






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. Involves cells that combat fungal and viral infection






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






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






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






17. Phloem - cambium - and xylem layers






18. Physical barier against bacterial invasion






19. Engulf and detroy foreign particles






20. Actively dividing - undifferentiated cells of a plant






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






22. Two upper chambers of the heart -thin walled






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






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






26. Thick-walled - muscular - elastic vessels that transport oxygenated blood away from the heart






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






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






29. 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






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






31. Carry oxygenated blood from the lungs to the heart






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






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






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






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






36. Systole and diastole - which together make a heartbeat






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






38. Modifies the rate of heart contraction






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






40. Excess interstitial fluid






41. Where blood flows through in arthropods






42. Branch into microscopic capillaries






43. Include arteries - veins - and capilleries






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






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






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






47. 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






48. Two lower chambers of the heart -extremely muscular






49. Fluid left after blood clotting






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