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






2. Primary organ of transport in the plant






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






4. Branches into a series of arteries






5. Leukocytes involved in immune response and the production of antibodies (B cells) or cytolysis of infected cells (T cells)






6. Outer layer of xylem that is alive






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






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






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






10. Leukocytes that phagocytize foreign matter and organisms such as bacteria






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






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






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






14. The period of cardiac muscle relaxation during which blood drains into all four chambers






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






16. Involves cells that combat fungal and viral infection






17. Two upper chambers of the heart -thin walled






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






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






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






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






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






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






24. Tissue involved in storage of nutrients and plant support






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






26. Include arteries - veins - and capilleries






27. Composed of nonspecific and specific defense mechanisms






28. Responsible for both of these immune mechanisms






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






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






31. Where blood flows through in arthropods






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






33. The driving force of the circulatory system






34. Supply plant cells with nutrients and remove waste products






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






36. Systole and diastole - which together make a heartbeat






37. Two layers thick and are the actively dividing - undifferentiated cells that give rise to xylem and phloem cell layers; as they divide - the cells near the phloem differentiate into phloem cells - and the cells near the xylem differentiate into xylem






38. 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






39. Branch into arterioles






40. 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






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






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






43. Carry oxygenated blood from the lungs to the heart






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






45. Blood is confined to blood vessel






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






47. Branch into microscopic capillaries






48. Phloem - cambium - and xylem layers






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






50. 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
