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. 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






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






3. Transport deoxygenated blood from the heart to the lungs






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






5. 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






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






7. Universal donor since it will not elicit a response from the recipient's immune system because it does not possess any surface antigens






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






9. Outer layer of xylem that is alive






10. The period during which the ventricles contract






11. Branches into a series of arteries






12. Branch into microscopic capillaries






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






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






15. Two lower chambers of the heart -extremely muscular






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






17. Oxygen carrying components of blood -formed from stem cells in the bone marrow where they lose their nuclei - mitochodnria - and membranous organelles






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






19. Attracted to the injury site phagocytize antigenic material






20. Excess interstitial fluid






21. 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)






22. The driving force of the circulatory system






23. 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






24. 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






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






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






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






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






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






30. Two upper chambers of the heart -thin walled






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






32. Tissue involved in storage of nutrients and plant support






33. Modifies the rate of heart contraction






34. Have three cusps and are located between the left ventricle and the aorta and between the right ventricle and the pumonary artery (the pulmonic valve)






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






36. Responsible for the proliferationof antibodies after exposure to antigens






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






38. 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






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






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






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






42. Composed of nonspecific and specific defense mechanisms






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






44. 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






45. Blood is confined to blood vessel






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






47. 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






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






49. 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






50. Fluid left after blood clotting
