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






2. 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






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






4. Carry oxygenated blood from the lungs to the heart






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






6. 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






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






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






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






10. Cardiac muscle contracts rhythmically without stimulation from the nervous system - producing impulses that spread through its internal conducting system






11. Fluid left after blood clotting






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






13. 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)






14. Secondary circulatory system distinct from the cardiovascular circulation - =vessels transport lymph to the cardiovascular system - thereby keeping fluid levels in the body constant






15. Outer layer of xylem that is alive






16. The driving force of the circulatory system






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






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






19. 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






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






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






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






23. Attracted to the injury site phagocytize antigenic material






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






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






26. Responsible for the proliferationof antibodies after exposure to antigens






27. Branch into arterioles






28. Include arteries - veins - and capilleries






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






30. Modifies the rate of heart contraction






31. 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






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






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






35. Transport deoxygenated blood from the heart to the lungs






36. Actively dividing - undifferentiated cells of a plant






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






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






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






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






41. Phloem - cambium - and xylem layers






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






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






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






45. Where blood flows through in arthropods






46. Where exchange occurs in arthropods






47. Primary organ of transport in the plant






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






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






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