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. When hemoglobin bind to oxygen






2. Physical barier against bacterial invasion






3. 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






4. Where blood flows through in arthropods






5. Primary organ of transport in the plant






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






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






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






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






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






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






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






13. 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






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






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






16. Epidermis (outer-bark) - cortex - phloem - cambium - xylem - and pith






17. Phloem - cambium - and xylem layers






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






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






20. The period during which the ventricles contract






21. Actively dividing - undifferentiated cells of a plant






22. Two upper chambers of the heart -thin walled






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






24. 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






25. 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






26. Modifies the rate of heart contraction






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






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






29. Composed of nonspecific and specific defense mechanisms






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






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






32. 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






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






34. Blood is confined to blood vessel






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






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






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






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






39. Include arteries - veins - and capilleries






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






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






42. Where exchange occurs in arthropods






43. Responsible for the proliferationof antibodies after exposure to antigens






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






45. Outer layer of xylem that is alive






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






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






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






49. Transport deoxygenated blood from the heart to the lungs






50. Branch into microscopic capillaries
