Questions 



How many barrels of blood does your heart pump between nine o'clock and three? 



Into what part of the heart does the blood flow through the vena cavaf 



What is the difference in structure between veins and arteries? What is the 

 difference in what they carry? 



What is the blood doing as it flows throughthe arteries? What change is taking 

 place in its appearance? 



Why must the blood flow to the liver? How would the digestive processes suffer 

 if the liver were unable to perform its work on the blood? 



Name the three circulatory systems, and tell briefly the work of each. 



How much do you weigh? How far would the force exerted by your heart in 

 one hour lift you? 



What do the lungs supply to the blood? What do they take from it? 



How did Dr. William Harvey discover the principles of blood-circulation? 



How long does it take a drop of blood to make its circuit from the left ventricle, 

 through the various systems, and back to its starting point? 



How many times in twenty-four hours does all the blood in your body pass 

 through your heart?
