A somewhat idealized graph of the speed of the blood in the ascending aorta during one beat of the heart appears as in the figure.
a) Approximately how far, in, does the blood move during one beat?
Express your answer to two significant figures and include the appropriate units
b)Assume similar data for the motion of the blood in your aorta. Estimate how many beats of the heart it will it take the blood to get from your heart to your brain.(Assume that the distance from your heart to your brain is 30)
Express your answer using one significant figure.
distance travelled =area under the graph
=1/2(bh) b-base h-height
number of beats =30/8=3.75 beats
