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. Converts fibrinogen (another plasma protein) into fibrin






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. Serve protective functions -aka WBC






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






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






6. Systole and diastole - which together make a heartbeat






7. 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






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






9. Carry oxygenated blood from the lungs to the heart






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






11. Branch into microscopic capillaries






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






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






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






15. Branches into a series of arteries






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






17. In annelids - five pairs of vessels that connect the dorsal vessel to the ventral vessel and function as additional pumps






18. Modifies the rate of heart contraction






19. 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)






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






21. The period during which the ventricles contract






22. 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






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






24. Phloem - cambium - and xylem layers






25. Composed of nonspecific and specific defense mechanisms






26. Tissue involved in storage of nutrients and plant support






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






28. Blood is confined to blood vessel






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






31. Branch into arterioles






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






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






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






35. Two upper chambers of the heart -thin walled






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






37. 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






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






39. 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






40. Two lower chambers of the heart -extremely muscular






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






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






43. Where exchange occurs in arthropods






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






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






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






47. Fluid left after blood clotting






48. Where blood flows through in arthropods






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






50. Transport deoxygenated blood from the heart to the lungs
