Teaching the Circulatory System

A teacher was giving a lesson on the circulation of the
blood. Trying to
make the matter clearer, he said, "Now, boys, if I stood on
my head the blood, as you know, would run into it, and I
should turn red in the face."

"Yes, sir," the boys said.

"Then why is it that while I am standing upright in the
ordinary position the blood doesn't run into my feet?"

A little fellow shouted, "Cause yer
feet ain't empty."
