Answer:

A number of factors can influence the respiration rate, such as:

Age – younger children generally have higher oxygen demands and therefore breath faster

Pain – pain will cause an increase in respiration rate

Emotion – emotion will cause an increase in respiration rate

Resistance from air passages – increased resistance (e.g. in asthma) prevents as much air entering the lungs during each cycle. The demand for oxygen will then increase, increasing the respiration rate.

Fever – fever increases the body’s demand for oxygen, increasing the respiration rate

Elasticity of the lungs – the less elastic the lungs, the less air can enter the lungs each cycle, increasing the respiration rate.

Chemical changes – chemical changes in the body, caused by hypoxia, metabolic disorders or medications / drugs, can cause the respiration rate to increase or decrease, depending on the stimulus
