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






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






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






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






5. When hemoglobin bind to oxygen






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






7. Heterotrophic cells that generally consume other cells or food particles -movement of gases and nutrients is a ccomplished by simple diffusion within the cell






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






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






10. Where blood flows through in arthropods






11. 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






12. 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






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






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






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






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






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






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






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






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






21. Engulf and detroy foreign particles






22. Involves cells that combat fungal and viral infection






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






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






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






26. 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






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






28. Two lower chambers of the heart -extremely muscular






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






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






31. Actively dividing - undifferentiated cells of a plant






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






33. Responsible for both of these immune mechanisms






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






35. The driving force of the circulatory system






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






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






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






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






40. Physical barier against bacterial invasion






41. Supply plant cells with nutrients and remove waste products






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






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






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






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






46. 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






47. Modifies the rate of heart contraction






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






49. Tissue involved in storage of nutrients and plant support






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