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. Branch into arterioles






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






3. Actively dividing - undifferentiated cells of a plant






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






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






6. 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






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






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






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






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. Involves cells that combat fungal and viral infection






12. 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






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






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






15. The production of antibodies during an immune response -can be conferred by vaccination






16. Include arteries - veins - and capilleries






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






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






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






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






21. Physical barier against bacterial invasion






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






24. Responsible for the proliferationof antibodies after exposure to antigens






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






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






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






28. Modifies the rate of heart contraction






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






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






31. 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






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






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






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






35. Transport deoxygenated blood from the heart to the lungs






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






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






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






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






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






41. Carry oxygenated blood from the lungs to the heart






42. Where exchange occurs in arthropods






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






44. Supply plant cells with nutrients and remove waste products






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






46. Branches into a series of arteries






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






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






49. Systole and diastole - which together make a heartbeat






50. Tissue involved in storage of nutrients and plant support
