The human heart...
1:39:12
...is a dense and powerful muscle...
1:39:16
...much like the organic equivalent
of mahogany...
1:39:20
...and notoriously difficult to burn.
1:39:28
It's about the size of a fist.
1:39:32
It provides the motor power
for the circulatory system.
1:39:37
The heart contains two atria,
two ventricles and four valves.

SIR WILLIAM:
It is, in effect, a single pump...
1:39:47
...powering a double circuit.
1:39:52
In the adult, the heart rate averages
70 to 80 beats a minute.
1:39:59
Such is the force of the heart beat...
1:40:02
...that if the body's largest artery,
the aorta, is severed...
1:40:09
...a six-foot jet ofblood...
1:40:14
...is released.
