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. Engulf and detroy foreign particles






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






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






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






5. Composed of nonspecific and specific defense mechanisms






6. Transport deoxygenated blood from the heart to the lungs






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






8. Responsible for both of these immune mechanisms






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






10. Tissue involved in storage of nutrients and plant support






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






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. Outer layer of xylem that is alive






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






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






16. When hemoglobin bind to oxygen






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






18. 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






19. Blood is confined to blood vessel






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






21. Carry oxygenated blood from the lungs to the heart






22. 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






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






24. Involves cells that combat fungal and viral infection






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






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






27. Branch into arterioles






28. 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






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






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






31. Serve protective functions -aka WBC






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






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






34. 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






35. 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)






36. AKA immunoglobulins (Igs) -defense mechanism that are complex proteins that recognize and bind to specific antigens and trigger the immune system to remove them -either attract other cells to phagocytize the antigen or cause the antigens to clump tog






37. Two upper chambers of the heart -thin walled






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






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






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






41. Excess interstitial fluid






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






43. Systole and diastole - which together make a heartbeat






44. Phloem - cambium - and xylem layers






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






46. Include arteries - veins - and capilleries






47. Attracted to the injury site phagocytize antigenic material






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






49. 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






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