Revision Notes
Exercise: Topic 15: Biology:
When you exercise your heart rate and breathing rate increase
...
The heart rate is measured at the wrist, as number
of beats per minute
...
The change of the rates:
During exercise your cells need to respire quickly and therefore need more oxygen
and glucose to get to cells faster
...
•
•
A fast heart rate indicates that the blood is pumped around the body faster
...
The removal of CO2 can be done quicker
...
When this happens, anaerobic respiration takes place
...
Some of it forms lactic acid which gives
pain
...
The increase
of heart rate allows the lactic acid to be carried away by the blood stream to the liver,
where it is then broken down
...
Cardiac output = stroke volume x heart rate
Stroke volume is the volume of blood pumped by the heart in one beat
...
Basically multiply (x) the two columns together
