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. Where blood flows through in arthropods






2. 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)






3. Modifies the rate of heart contraction






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






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






6. Converts fibrinogen (another plasma protein) into fibrin






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






8. Two lower chambers of the heart -extremely muscular






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






10. Composed of nonspecific and specific defense mechanisms






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






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






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






14. Branches into a series of arteries






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






16. Attracted to the injury site phagocytize antigenic material






17. 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






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






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






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






21. Carry oxygenated blood from the lungs to the heart






22. Phloem - cambium - and xylem layers






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






24. Have body walls that are two cells thick -all cels are direct contact with either the internal or external environments so there is no need for a specialized circulatory system






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






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






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






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






29. Two upper chambers of the heart -thin walled






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






31. 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






32. 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






33. 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






34. 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






35. When hemoglobin bind to oxygen






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






37. Pumps oxygenated blood into systemic circulation (throughout the body)






38. 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






39. Responsible for both of these immune mechanisms






40. Outer layer of xylem that is alive






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






42. Branch into arterioles






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






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






45. Fluid left after blood clotting






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






47. Physical barier against bacterial invasion






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






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






50. Primary organ of transport in the plant
