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. 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






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






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






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






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






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






7. 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






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






9. Actively dividing - undifferentiated cells of a plant






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






11. Physical barier against bacterial invasion






12. 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






13. Skin - mucous-coated epithelia - macrophages - inflammatory - interferons






14. Systole and diastole - which together make a heartbeat






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






16. 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






17. 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






18. Primary organ of transport in the plant






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






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






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






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






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. 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






25. 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)






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






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






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






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






30. Branches into a series of arteries






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






32. 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






33. 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






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






35. Where exchange occurs in arthropods






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






37. Serve protective functions -aka WBC






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






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






40. Supply plant cells with nutrients and remove waste products






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






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






43. Excess interstitial fluid






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






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






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






47. Include arteries - veins - and capilleries






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






49. Two lower chambers of the heart -extremely muscular






50. Blood is confined to blood vessel
