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. Where exchange occurs in arthropods






2. Include arteries - veins - and capilleries






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






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






5. Supply plant cells with nutrients and remove waste products






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






7. Transport deoxygenated blood from the heart to the lungs






8. 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






9. Converge into venules and eventually into veins - leading deoxygenated blood back toward the heart






10. 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






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






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






13. Phloem - cambium - and xylem layers






14. Responsible for the proliferationof antibodies after exposure to antigens






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






16. Where blood flows through in arthropods






17. 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






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






19. Branch into microscopic capillaries






20. 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






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






22. Outer layer of xylem that is alive






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






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






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






26. Converts fibrinogen (another plasma protein) into fibrin






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






28. Blood is confined to blood vessel






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






30. Fluid left after blood clotting






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






32. Serve protective functions -aka WBC






33. Actively dividing - undifferentiated cells of a plant






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






35. The period during which the ventricles contract






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






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






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






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






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






41. Involves cells that combat fungal and viral infection






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






43. 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






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






45. Branch into arterioles






46. 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)






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






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






49. Responsible for generating the force that propels systematic circulation and pumps against a higher resistance






50. Excess interstitial fluid
