During exercise, an individual\'s ventilation rate increases even before oxygen and carbon dioxide levels in the blood change. This anticipatory modification of respiratory rate is best described as (a):

(a) Negative feedback loop.

(b) Positive feedback loop.

(c) Feedforward control.

(e) None of the above.

Solution

During exercise, an individual\'s ventilation rate increases even before oxygen and carbon dioxide levels in the blood change. This anticipatory modification of respiratory rate is best described as

(c) Feedforward control

Biological systems operate on a mechanism of inputs and outputs, each causing a certain event. These are important as they allow living organism to maintain homeostasis In some circumstances, it is possible to measure the disturbance before the disturbance has influence the system. The effect of the disturbance is thus reduced by measuring it and generating a control signal that counteracts it. This is called feedforward control. It mainly focus on inputs, as during exercise the oxgen and carbon dioxide level in the blood changes results in incresed ventilation rate, feed forward control might measures the oxyen and carbondioxide levels in the blood and thus equalising the ventilation rate.
