Afternoon chaps....quick biology question?

does a persons respiratory system increase or decrease when the body temparature is high?....Ie no excercise or sex is involved...the body is in static position...!

sensible answers please?!

If body temp is high at rest, then metabolic rate is higher than normal so heart & lungs will be working a little quicker than normal.

thankyou....

If you body is carrying excessive heat you get rid of it by dilating (opening up wider) the blood vessels in your skin to exchange more heat with your sweat, which would slightly drop your peripheral blood pressure so your heartrate might increase a smidgen, but your respiration would not be effected.

The most common reason for a high temperature is an infection or inflammatory process. Part of this response is an increase in metabolic rate, increased involuntary skeletal muscle activity (shivering right through to rigors). The most common infections are respiratory infections, and lower respiratory infections would naturally give an increased respiratory rate - this is a marker of their severity. In addition, the distress of a fever or illness can result in increased respiratory rate. Reduction in respiratory rate in the context of serious illness is usually a grave sign, along with cyanosis (blue), reduced conscious level/confusion, other late signs are low temperature, very slow pulse (after initial rise).
