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






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






3. Where blood flows through in arthropods






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






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






6. 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






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






8. Involves cells that combat fungal and viral infection






9. Tissue involved in storage of nutrients and plant support






10. Carry oxygenated blood from the lungs to the heart






11. Blood is confined to blood vessel






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






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






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






15. The driving force of the circulatory system






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






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






18. 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






19. Primary organ of transport in the plant






20. 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






21. Converts fibrinogen (another plasma protein) into fibrin






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






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






24. Actively dividing - undifferentiated cells of a plant






25. Initiated by the body in response to physical damage and often accompanied by fever






26. Physical barier against bacterial invasion






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






28. 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






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






30. Two lower chambers of the heart -extremely muscular






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






32. Include arteries - veins - and capilleries






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






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






35. Responsible for the proliferationof antibodies after exposure to antigens






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






37. 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






38. 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






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






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






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






42. Fluid left after blood clotting






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






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






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






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






47. Attracted to the injury site phagocytize antigenic material






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






49. Branch into microscopic capillaries






50. Two upper chambers of the heart -thin walled
