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






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






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






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






5. 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






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






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






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






9. Tissue involved in storage of nutrients and plant support






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






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






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






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






14. Responsible for the proliferationof antibodies after exposure to antigens






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






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






17. Where exchange occurs in arthropods






18. 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






19. Attracted to the injury site phagocytize antigenic material






20. Branches into a series of arteries






21. Blood transports nutrients and O2 to tissue and wastes and CO2 from tissue -transport of gases - transport of nutrients and wste - and clotting






22. Include arteries - veins - and capilleries






23. Blood is confined to blood vessel






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






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






26. 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






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






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






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






30. Converts fibrinogen (another plasma protein) into fibrin






31. Carry oxygenated blood from the lungs to the heart






32. Two upper chambers of the heart -thin walled






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






34. Where blood flows through in arthropods






35. Transport deoxygenated blood from the heart to the lungs






36. 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






37. Engulf and detroy foreign particles






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






39. The driving force of the circulatory system






40. Fluid left after blood clotting






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






42. Branch into microscopic capillaries






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






44. Actively dividing - undifferentiated cells of a plant






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






46. 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)






47. 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






48. Serve protective functions -aka WBC






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






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