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






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






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






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






5. 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






6. Outer layer of xylem that is alive






7. 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)






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






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






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






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






12. 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






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






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






15. Systole and diastole - which together make a heartbeat






16. The period during which the ventricles contract






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






18. Attracted to the injury site phagocytize antigenic material






19. 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






20. Physical barier against bacterial invasion






21. Responsible for the proliferationof antibodies after exposure to antigens






22. Lying between the phloem and xylem - is a type of meristem called lateral meristem that provides for lateral growth of the stem by adding to the phloem or xylem






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






24. 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






25. Primary organ of transport in the plant






26. When hemoglobin bind to oxygen






27. (earthworm) uses a closed circulatory system to deliver materials to cells that are not in direct contact with the external environment






28. Transport deoxygenated blood from the heart to the lungs






29. Excess interstitial fluid






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






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






32. Engulf and detroy foreign particles






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






34. Blood is confined to blood vessel






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






36. Actively dividing - undifferentiated cells of a plant






37. Two upper chambers of the heart -thin walled






38. Responsible for both of these immune mechanisms






39. Where exchange occurs in arthropods






40. Universal recipient as it has neither anti-A nor anti-B antibodies






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






42. 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






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






44. 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






45. 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






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






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






48. 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






49. Branch into microscopic capillaries






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