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. Functions as the main heart by coordinated contractions in annelids






2. Transport deoxygenated blood from the heart to the lungs






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






4. Attracted to the injury site phagocytize antigenic material






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






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






7. Fluid left after blood clotting






8. 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






9. Actively dividing - undifferentiated cells of a plant






10. Systole and diastole - which together make a heartbeat






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






12. Carry oxygenated blood from the lungs to the heart






13. 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






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






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






16. Two upper chambers of the heart -thin walled






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






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






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






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






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






22. Involves cells that combat fungal and viral infection






23. 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)






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






25. Lying between the phloem and xylem - is a type of meristem called lateral meristem that provides for lateral growth of the stem by adding to the phloem or xylem






26. Carries impuls of AV node which branches into the right and left bundle branches - and through the Purkinje fibers in the walls of ventircles - generating a strong contraction






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






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






29. Where exchange occurs in arthropods






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






31. Responsible for the proliferationof antibodies after exposure to antigens






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






33. Produced by cells under viral attack and diffuse to other cells - where they help prevent the spread of the virus






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






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






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






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






38. 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






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






40. 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)






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






42. 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






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






44. Tissue involved in storage of nutrients and plant support






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






46. Composed of nonspecific and specific defense mechanisms






47. Outer layer of xylem that is alive






48. Branch into microscopic capillaries






49. 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






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