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. Two upper chambers of the heart -thin walled






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






4. Tissue involved in storage of nutrients and plant support






5. 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






6. Systole and diastole - which together make a heartbeat






7. 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






8. Two lower chambers of the heart -extremely muscular






9. Converts fibrinogen (another plasma protein) into fibrin






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






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






12. Responsible for the proliferationof antibodies after exposure to antigens






13. Branch into microscopic capillaries






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






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






16. Carry oxygenated blood from the lungs to the heart






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






18. Outer layer of xylem that is alive






19. The period during which the ventricles contract






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






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






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






23. Branches into a series of arteries






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






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






26. 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






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






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






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






30. 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)






31. 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






32. Physical barier against bacterial invasion






33. Modifies the rate of heart contraction






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






35. Involves cells that combat fungal and viral infection






36. 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)






37. 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






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






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






40. Responsible for both of these immune mechanisms






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






42. Supply plant cells with nutrients and remove waste products






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






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






45. 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






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






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






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






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






50. Branch into arterioles
