Last month our article ended with
an interesting question. "Did you know that the heart muscle, which in
the average adult weighs less than a pound, pumps about ___________ gallons a day, which is
about ________ pounds of blood a day?" The surprising answer is that the heart pumps
about 2,000 gallons a day, which is about 20,000 pounds a day! This can
vary up or down depending upon activity level. The human heart weighs
8-10 oz., and is the size of a human fist, and beats on average 100,000
times per day. The heart muscle is an amazing pump, and is designed to
last a lifetime!
