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






2. Physical barier against bacterial invasion






3. Responsible for both of these immune mechanisms






4. Functions to absorb materials through the root hairs and anchor the plant -provide storage for energy reserves






5. Branches into a series of arteries






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






7. Supply plant cells with nutrients and remove waste products






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






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






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






11. Fluid left after blood clotting






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






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






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






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






16. 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






17. Excess interstitial fluid






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






19. Blood is confined to blood vessel






20. Outer layer of xylem that is alive






21. Primary organ of transport in the plant






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






23. Transport deoxygenated blood from the heart to the lungs






24. 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






25. Phloem - cambium - and xylem layers






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. An individual is injected witha weakened - inactive - or related form of a particular antigen - which stimulates the immune system to produce specific antibodies against it






28. 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






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






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. 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






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






33. Carry oxygenated blood from the lungs to the heart






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






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






36. Serve protective functions -aka WBC






37. Tissue involved in storage of nutrients and plant support






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






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






40. The period during which the ventricles contract






41. Engulf and detroy foreign particles






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






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






44. Converts fibrinogen (another plasma protein) into fibrin






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






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






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






48. Involves cells that combat fungal and viral infection






49. Where blood flows through in arthropods






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