Question

A feedback mechanism that increases respiration rate to exhale more co2 would be:_________

Answer 1

As your body needs more oxygen during exercising and produces more carbon dioxide, this might result in a high respiratory rate.

During exercise, your breathing may occur 3–4 times more frequently. Hyperpnea, or rapid, deep breathing, is the body's natural response to increased carbon dioxide generation. The pace of breathing increases along with the blood's concentration of carbon dioxide. The pH of the blood changes dramatically as carbon dioxide levels rise. The chemoreceptors in the medulla oblongata, a part of the hindbrain that controls respiration, detect this shift. To expel the additional carbon dioxide and breathe in more oxygen, the respiratory center speeds up breathing.
