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. 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






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






3. Systole and diastole - which together make a heartbeat






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






5. Branch into arterioles






6. Include arteries - veins - and capilleries






7. Thick-walled - muscular - elastic vessels that transport oxygenated blood away from the heart






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






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






10. Fluid left after blood clotting






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






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






13. Serve protective functions -aka WBC






14. Where exchange occurs in arthropods






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






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






17. Carry oxygenated blood from the lungs to the heart






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






19. When hemoglobin bind to oxygen






20. Supply plant cells with nutrients and remove waste products






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






22. Severe anemia for the fetus caused by Rh+ fetus






23. 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






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






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






26. Transport deoxygenated blood from the heart to the lungs






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






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






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






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






31. 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






32. Actively dividing - undifferentiated cells of a plant






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






34. 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






35. Branches into a series of arteries






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






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






38. Two upper chambers of the heart -thin walled






39. Responsible for the proliferationof antibodies after exposure to antigens






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






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






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






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






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






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






46. 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






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






48. Primary organ of transport in the plant






49. Composed of nonspecific and specific defense mechanisms






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