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. Tissue involved in storage of nutrients and plant support






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






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






4. 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






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






6. When hemoglobin bind to oxygen






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. 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






9. Two upper chambers of the heart -thin walled






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






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






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






13. Transport deoxygenated blood from the heart to the lungs






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






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






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






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






18. Pumps deoxygenated blood into pulmonary circulation (toward the lungs)






19. 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






20. Composed of nonspecific and specific defense mechanisms






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






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






23. Include arteries - veins - and capilleries






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






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






26. 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






27. 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






28. Carry oxygenated blood from the lungs to the heart






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






30. Fluid left after blood clotting






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






32. 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






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






34. Branch into microscopic capillaries






35. Where exchange occurs in arthropods






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






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






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






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






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






41. Phloem - cambium - and xylem layers






42. 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






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






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






45. Converts fibrinogen (another plasma protein) into fibrin






46. Branches into a series of arteries






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






48. Where blood flows through in arthropods






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






50. 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
