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. Branch into arterioles






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






3. 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)






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






5. 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






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






7. Composed of nonspecific and specific defense mechanisms






8. Located between the atria and ventricles on both sides of the heart - prevent backflow of blood into the atria






9. Cells that are thick walled - often hollow cells located on the inside of the vascular bundle that carry water and minerals up the plant - and their thick walls give the plant its rigid support






10. Involves cells that combat fungal and viral infection






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






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






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






14. Leukocytes that phagocytize foreign matter and organisms such as bacteria






15. Branches into a series of arteries






16. 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






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






18. Where blood flows through in arthropods






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






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






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






22. Phloem - cambium - and xylem layers






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






24. Defined as the total volume of blood the left ventricle pumps out per minute = heart rate (number of BPM) x stroke volume (volume of blood pumped out of the left ventricle per contraction)






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






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






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






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






29. Fluid left after blood clotting






30. Engulf and detroy foreign particles






31. 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






32. Two lower chambers of the heart -extremely muscular






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






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






35. Coat the damaged area and trap blood cells to form a clot






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






37. Converts fibrinogen (another plasma protein) into fibrin






38. 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






39. When hemoglobin bind to oxygen






40. Two upper chambers of the heart -thin walled






41. Outer layer of xylem that is alive






42. Include arteries - veins - and capilleries






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






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






45. Tissue involved in storage of nutrients and plant support






46. Attracted to the injury site phagocytize antigenic material






47. The driving force of the circulatory system






48. The period during which the ventricles contract






49. Responsible for the proliferationof antibodies after exposure to antigens






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