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






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






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






4. The period of cardiac muscle relaxation during which blood drains into all four chambers






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






6. Attracted to the injury site phagocytize antigenic material






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






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






9. The driving force of the circulatory system






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






11. Where blood flows through in arthropods






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






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






14. 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






15. When hemoglobin bind to oxygen






16. 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






17. Outer layer of xylem that is alive






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






19. Excess interstitial fluid






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






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






22. Thin walled cells on the outside of the vascular bundle that transport nutrients down the stem -are living and include sieve tube cells and companion cells






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






24. Branches into a series of arteries






25. Where exchange occurs in arthropods






26. 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






27. 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






28. Responsible for both of these immune mechanisms






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






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






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






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






33. Responsible for the proliferationof antibodies after exposure to antigens






34. Branch into microscopic capillaries






35. Systole and diastole - which together make a heartbeat






36. Two lower chambers of the heart -extremely muscular






37. Primary organ of transport in the plant






38. Two upper chambers of the heart -thin walled






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






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






41. Physical barier against bacterial invasion






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






43. Engulf and detroy foreign particles






44. Modifies the rate of heart contraction






45. Fluid left after blood clotting






46. Cell fragments that lack nuclei and are involved in clot formation -involved in injury repair






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






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






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






50. Include arteries - veins - and capilleries
