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. Composed of nonspecific and specific defense mechanisms






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






3. Branch into microscopic capillaries






4. Supply plant cells with nutrients and remove waste products






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






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






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






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






9. Systole and diastole - which together make a heartbeat






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






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






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






13. Excess interstitial fluid






14. Blood is confined to blood vessel






15. Leukocytes that phagocytize foreign matter and organisms such as bacteria






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






17. Where exchange occurs in arthropods






18. Branch into arterioles






19. The driving force of the circulatory system






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






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






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






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. When hemoglobin bind to oxygen






25. 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






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






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






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






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






30. 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






31. 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






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






33. 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






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






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






36. Physical barier against bacterial invasion






37. 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






38. Serve protective functions -aka WBC






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






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






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






42. Where blood flows through in arthropods






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






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






45. 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






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






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






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






49. Phloem - cambium - and xylem layers






50. The period during which the ventricles contract
