  1. Circulatory System and Blood Review

  2. Which of the following is NOT a function of the circulatory system To transport nutrients, waste and chemical messages Control body functions (ex. Movement) Maintaining homeostasis through regulation of pH levels, internal body temperature and clotting to prevent blood loss Plays a role in combatting disease and infection

  3. In an Open Circulatory System the blood: Travels through a complete network of blood vessels Travels through tiny blood vessels called capillaries to supply oxygen to the body tissues Reflects as red because of the iron atoms used in hemoglobin used to bond with the oxygen molecules Mixes with the other body fluids and bathes the cells directly

  4. A Closed Circulatory System: Has a complete network of blood vessels Has Hemolypmh, a mixture of blood and body fluids that is pumped through the body cavities Draws the blood back towards the heart, as the heart relaxes from contraction Does not have a complete network of blood vessels

  5. The 4 main components of blood are: Erythrocytes, platelets, plasma and red blood cells Red blood cells, platelets, plasma and white blood cells Red blood cells, white blood cells, plasma and nuclei Hemocyanin, red blood cells, white blood cells, and platelets

  6. Which of the following contains a nucleus? Red blood cells Platelets Plasma White blood cells

  7. The primary function of RBC’s is to: Fight infection and disease Carry oxygen to body tissues Create blood clots Phagocytosis

  8. RBC’s in human blood use this to carry oxygen through the blood stream. Hemocyanin with 4 copper atoms Hemoglobin with 4 iron atoms Hemoglobin with 4 copper atoms Hemocyanin with 4 iron atoms

  9. Hemolymph Is another word for blood Is found in humans Is found in the closed circulatory system Is a mixture of blood and body fluid found in animals with an open circulatory system

  10. Which of the following are the correct order of phagocytosis? Engulfment by endocytosis, formation of phagosome, phagosome-lysosome merger phagolysosome, killing and digestion of the invading organism, exocytosis of the debris Engulfment by endocytosis, phagosome-lysosome merger phagolysosome, formation of phagosome, killing and digestion of the invading organism, exocytosis of the debris Engulfment by endocytosis, formation of phagosome, phagosome-lysosome merger phagolysosome, exocytosis of the debris, killing and digestion of the invading organism Exocytosis of the debris , formation of phagosome, phagosome-lysosome merger phagolysosome, killing and digestion of the invading organism, engulfment by endocytosis

  11. Of the 5 types of WBC’s which 3 of them use phagocytosis to fight infection? Neutrophil, monocyte, basophil Basophil, monocyte, lymphocyte Eosinophil, neutrophil, monocyte Eosinophil, neutrophil, basophil

  12. What is the primary function of platelets? To transport oxygen to body tissues To fight disease and infection To transport nutrients and waste through the blood stream To maintain homeostasis by preventing blood loss

  13. There are good blood blots, and bad blood clots. True or False True False

  14. Blood clots in blood vessels can be caused by a variety of factors come of these include: Physical inactivity and smoking Cancer and rheumatoid arthritis Some medications and a genetic predisposition to “sticky blood” All of the above
