1. Carbondioxide concentration
The high concentration of carbon dioxide in the
lood also the rate of gaseous exchange increase this is due to provide the
tissue adequate amount of oxygen and eliminate large amount of carbon dioxide
2. Concentration of Haemoglobin
Haemoglobin is a structure responsible for
transportation of respiratory gases from the lungs to the tissue and back.
Therefore, efficient transportation o gases only take place when the body has adequate amount of
haemohglobin
3. Physical activity
A more active body require more oxygen than a less
active body as a result, gaseous exchange take place faster when there is
increased body activity.
4. Health status of the body.
Generally, the rate of gaseous exchange increase
when somebody is sick. This is as a result of increased metabolism by the liver
in order to either remove the toxins released by disease causing microorganisms
or breakdown the drugs taken.
5.Age
Young people generally are more active than old people;
also, a lot of growth process take place in the bodies of young people, this
increase the demand of oxygen and therefore increases the breathing rate
