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. 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






2. Carry oxygenated blood from the lungs to the heart






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






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






5. Outer layer of xylem that is alive






6. 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






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






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






9. Responsible for the proliferationof antibodies after exposure to antigens






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






11. Inappropriate response to certain foods and pollen that cause the body to form antibodies and release histamine






12. Innervates the heart via the cervical and upper thoracic ganglia and causes an increase in the ehart rate






13. 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






14. Where exchange occurs in arthropods






15. Branches into a series of arteries






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






17. Phloem - cambium - and xylem layers






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






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






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






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






22. Serve protective functions -aka WBC






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






24. Primary organ of transport in the plant






25. Excess interstitial fluid






26. Composed of nonspecific and specific defense mechanisms






27. Smallest diameter of all three types of vessels; red blood cells must often travel through them single file






28. Transport deoxygenated blood from the heart to the lungs






29. 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






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






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






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






33. Physical barier against bacterial invasion






34. 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






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






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






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






38. Where blood flows through in arthropods






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






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






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






42. 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






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






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






46. 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)






47. Systole and diastole - which together make a heartbeat






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






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






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