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. Branches into a series of arteries






2. With the aid of its cofactors calcium and Vitamin K - converts the inactive plasma protein prothrombin to its active form - thrombin






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






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






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






6. Tissue involved in storage of nutrients and plant support






7. Actively dividing - undifferentiated cells of a plant






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






9. Systole and diastole - which together make a heartbeat






10. Serve protective functions -aka WBC






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






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






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






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






15. Where exchange occurs in arthropods






16. Transport deoxygenated blood from the heart to the lungs






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






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






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






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






21. Where blood flows through in arthropods






22. Responsible for the proliferationof antibodies after exposure to antigens






23. Physical barier against bacterial invasion






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






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






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






27. The driving force of the circulatory system






28. Excess interstitial fluid






29. Branch into arterioles






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






31. Branch into microscopic capillaries






32. 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






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






34. Engulf and detroy foreign particles






35. Two upper chambers of the heart -thin walled






36. 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






37. 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






38. Include arteries - veins - and capilleries






39. Two lower chambers of the heart -extremely muscular






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






41. When hemoglobin bind to oxygen






42. Blood is confined to blood vessel






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






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






45. Supply plant cells with nutrients and remove waste products






46. Functions as the main heart by coordinated contractions in annelids






47. Used to lower the immune response to transplants and decrease the likelihood of rejection






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






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






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