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. AKA immunoglobulins (Igs) -defense mechanism that are complex proteins that recognize and bind to specific antigens and trigger the immune system to remove them -either attract other cells to phagocytize the antigen or cause the antigens to clump tog






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






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






4. Phloem - cambium - and xylem layers






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






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






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






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






9. Excess interstitial fluid






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






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






12. Responsible for the proliferationof antibodies after exposure to antigens






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






14. Attracted to the injury site phagocytize antigenic material






15. Branch into microscopic capillaries






16. Branches into a series of arteries






17. 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






18. Converts fibrinogen (another plasma protein) into fibrin






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






20. Involves the production of antibodies and cell-mediated immunity






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






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






23. Tissue involved in storage of nutrients and plant support






24. 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)






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






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






27. 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






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






29. Transport deoxygenated blood from the heart to the lungs






30. When hemoglobin bind to oxygen






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






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






33. 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






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






35. Supply plant cells with nutrients and remove waste products






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






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






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






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






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






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






42. Primary organ of transport in the plant






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






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






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






46. Two upper chambers of the heart -thin walled






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






48. Composed of nonspecific and specific defense mechanisms






49. 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






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