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






2. Fluid left after blood clotting






3. Supply plant cells with nutrients and remove waste products






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






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






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






7. Blood is confined to blood vessel






8. 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






9. Include arteries - veins - and capilleries






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






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






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






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






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






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






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






17. Where blood flows through in arthropods






18. 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






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






20. 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






21. Actively dividing - undifferentiated cells of a plant






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






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






24. 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






25. Physical barier against bacterial invasion






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






27. Two upper chambers of the heart -thin walled






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






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






30. 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






31. 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






32. 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)






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






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






35. Branches into a series of arteries






36. The period during which the ventricles contract






37. Attracted to the injury site phagocytize antigenic material






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






39. Modifies the rate of heart contraction






40. Converts fibrinogen (another plasma protein) into fibrin






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






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






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






44. Responsible for both of these immune mechanisms






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






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






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






48. Systole and diastole - which together make a heartbeat






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






50. 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
