Circulatory & respiratory
systems
Heart
 Blood vessels
arteries > arterioles
(away from heart)
veins > venules
(returning to heart)
capilliaries

Circulatory & respiratory
systems



Work together to get oxygenated blood to the working
muscles.
Oxygenated blood is picked up at the lungs, it returns
to the heart and is then pumped around body via the
arterial system, delivering oxygen and nutrients as it
goes.
Deoxygenated blood (inc waste products such as
carbon dioxide) returns to heart via venous system and
is pumped back to lungs to pick up more oxygen.
Better physical performance

How efficient our respiratory and circulatory systems are at
working together will affect our physical performance

The more efficient our respiratory system is, the greater will be
the volume of oxygen getting into our lungs, and from there into
our bloodstream.
The more efficient our circulatory system is, the greater will be
the volume of this oxygen rich blood being pumped to our
muscles and organs enabling them to work efficiently for longer.


BOTH SYSTEMS CAN BE IMPROVED BY TRAINING
Benefits of exercise to circulatory
system

Stronger cardiac muscle

Increased stroke volume
Increased cardiac output
(stroke volume x beats per minute)


Lower resting heart rate
Benefits of exercise to respiratory
system

Improved gaseous exchange

Increased vital capacity

Increased tidal volume

Improved O2 debt tolerance
