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. Primary organ of transport in the plant






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






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






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






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






6. Actively dividing - undifferentiated cells of a plant






7. Tissue involved in storage of nutrients and plant support






8. Fluid left after blood clotting






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






10. 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)






11. Branch into arterioles






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






13. Relatively thinly walled - inelastic vessels that conduct deoxygenated blood toward the heart






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






15. Responsible for the proliferationof antibodies after exposure to antigens






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






17. 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






18. Supply plant cells with nutrients and remove waste products






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






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






21. Carry oxygenated blood from the lungs to the heart






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






23. The production of antibodies during an immune response -can be conferred by vaccination






24. 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






25. 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






26. Composed of nonspecific and specific defense mechanisms






27. 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






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






29. Outer layer of xylem that is alive






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






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






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






33. Physical barier against bacterial invasion






34. Include arteries - veins - and capilleries






35. 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






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






37. Blood is confined to blood vessel






38. Oxygen carrying components of blood -formed from stem cells in the bone marrow where they lose their nuclei - mitochodnria - and membranous organelles






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






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






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






42. 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






43. 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






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






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






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






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






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






49. 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






50. Where blood flows through in arthropods
