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. Lined in passages - which filter and trap foreign particles






2. Branches into a series of arteries






3. Fluid left after blood clotting






4. Phloem - cambium - and xylem layers






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






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






7. Carry oxygenated blood from the lungs to the heart






8. 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)






9. Cell fragments that lack nuclei and are involved in clot formation -involved in injury repair






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






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






12. Where blood flows through in arthropods






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






14. The driving force of the circulatory system






15. Responsible for the proliferationof antibodies after exposure to antigens






16. Converts fibrinogen (another plasma protein) into fibrin






17. 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






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






19. Systole and diastole - which together make a heartbeat






20. Outer layer of xylem that is alive






21. 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)






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






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






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






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






26. Branch into arterioles






27. Valve on the right side of the heart has three cusps






28. The period during which the ventricles contract






29. Have open circulatory systems in which blood (interstitial fluid) is in direct contact with the body tissues -blood is circulated primarily by body movements






30. 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






31. Tissue involved in storage of nutrients and plant support






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






33. When hemoglobin bind to oxygen






34. Secondary circulatory system distinct from the cardiovascular circulation - =vessels transport lymph to the cardiovascular system - thereby keeping fluid levels in the body constant






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






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






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






38. Oxygen carrying components of blood -formed from stem cells in the bone marrow where they lose their nuclei - mitochodnria - and membranous organelles






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






40. 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






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






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






43. Blood is confined to blood vessel






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






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






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






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






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






49. 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






50. Actively dividing - undifferentiated cells of a plant
