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. 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






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






3. When hemoglobin bind to oxygen






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






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






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






7. 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)






8. 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






9. Two lower chambers of the heart -extremely muscular






10. Engulf and detroy foreign particles






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






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






13. Run up and down the stem at the center and contains xylem - phloem - and cambium cells






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






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






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






17. Where exchange occurs in arthropods






18. 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






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






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






21. Valve on the right side of the heart has three cusps






22. Branches into a series of arteries






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






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






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






26. Tissue involved in storage of nutrients and plant support






27. The period during which the ventricles contract






28. 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






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






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






31. Systole and diastole - which together make a heartbeat






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






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






34. Where blood flows through in arthropods






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






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






37. Phloem - cambium - and xylem layers






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






39. Transport deoxygenated blood from the heart to the lungs






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






42. Involves cells that combat fungal and viral infection






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






44. Composed of nonspecific and specific defense mechanisms






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






46. Fluid left after blood clotting






47. Actively dividing - undifferentiated cells of a plant






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






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






50. Branch into arterioles
