blood to the rest of
the body for use.
The right side pumps deoxygenated blood to the lungs to pick up oxygen.
Blood flows around the body in a ‘figure of eight’ circuit, passing through the heart twice on each circuit. Hence the name the Double Pump System.
There are 2 separate ‘loops’ to the circuit:
The top loop – carries blood from the heart to the lungs and back.
The bottom loop – carries blood from the heart to all over the body and back.
Heart rate is:
“The number of times the heart beats each minute”
“the volume of blood pumped out of the heart during one contraction”
“the amount of blood ejected from the heart in one minute”

“The volume of air inspired and expired with each normal breath at rest or during exercise ”
“the maximum amount of air that can be made to pass into and out of the lungs by the most forceful inspiration and expiration”
“the amount of oxygen consumed during recovery above that which would have ordinarily been consumed in the same time at rest”
