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






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






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






4. Actively dividing - undifferentiated cells of a plant






5. 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






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






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






8. 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






9. Responsible for the proliferationof antibodies after exposure to antigens






10. Supply plant cells with nutrients and remove waste products






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






12. 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






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






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






15. Converts fibrinogen (another plasma protein) into fibrin






16. 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)






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






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






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






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






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






22. Phloem - cambium - and xylem layers






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






24. Branch into microscopic capillaries






25. Outer layer of xylem that is alive






26. Located between the atria and ventricles on both sides of the heart - prevent backflow of blood into the atria






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






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






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






30. Fetal red blood cells (which will have the Rh factor) enter maternal circulation during birth which cause the anti-Rh antibodies she produced when sensitized by the first birth may cross the placenta and destroy fetal red blood cells






31. Two upper chambers of the heart -thin walled






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






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






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






35. 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






36. Where blood flows through in arthropods






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






38. Physical barier against bacterial invasion






39. Include arteries - veins - and capilleries






40. Primary organ of transport in the plant






41. 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






42. A small mass of specialized tissue located in the wall of the right atrium regulates/originates an ordinary cardiac contraction -spreads impulses through both atria - stimulating them to contract simultaneously






43. Excess interstitial fluid






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






45. Carry oxygenated blood from the lungs to the heart






46. Branch into arterioles






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






48. When hemoglobin bind to oxygen






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






50. Systole and diastole - which together make a heartbeat
