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. Actively dividing - undifferentiated cells of a plant






2. Fluid left after blood clotting






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






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






5. 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






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






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






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






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






10. Two upper chambers of the heart -thin walled






11. 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






12. Branches into a series of arteries






13. Primary organ of transport in the plant






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






15. Where blood flows through in arthropods






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






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






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






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






20. 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






21. Transport deoxygenated blood from the heart to the lungs






22. Serve protective functions -aka WBC






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






24. Blood is confined to blood vessel






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






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






27. 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






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






29. 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)






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






31. Tissue involved in storage of nutrients and plant support






32. 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






33. Composed of nonspecific and specific defense mechanisms






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






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






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






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






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






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






40. Excess interstitial fluid






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






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






43. 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






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






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






46. Responsible for both of these immune mechanisms






47. Valve on the left side of the heart that has two cusps






48. Systole and diastole - which together make a heartbeat






49. Cell-surface proteins that are macromolecules that are foreign to the host organism and trigger an immune response ex: ABO group and the Rh factor






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