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






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






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






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






5. Physical barier against bacterial invasion






6. Composed of muscular - four-chambered heart - a network of blood vessels - and the blood itself






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






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






9. Branches into a series of arteries






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






11. Modifies the rate of heart contraction






12. 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






13. 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






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






15. Responsible for both of these immune mechanisms






16. Attracted to the injury site phagocytize antigenic material






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






18. Two upper chambers of the heart -thin walled






19. Tissue involved in storage of nutrients and plant support






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






21. 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






22. Smallest diameter of all three types of vessels; red blood cells must often travel through them single file






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






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






25. Fluid left after blood clotting






26. Two lower chambers of the heart -extremely muscular






27. Transport deoxygenated blood from the heart to the lungs






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






29. 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






30. 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






31. Serve protective functions -aka WBC






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






33. Include arteries - veins - and capilleries






34. 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






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






36. 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






37. Branch into arterioles






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






39. Excess interstitial fluid






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






41. 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






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






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






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






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






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






47. 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






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






49. Branch into microscopic capillaries






50. Where blood flows through in arthropods
