Name the part that plays major role in respiratory movements in woman .

Explanation

In human beings the respiratory movements are regulated by neural system. special centre present in the medulla region of brain, called .respiratory rhythm centre. is primarily responsible for this regulation.
2. Another centre present in the pons of the brain stem called .pneumotaxic centre. can moderate the functions of the respiratory rhythm centre. Neural signal from and this centre can reduce the duration of inspiration and thereby alter the respiration rate.
3. A chemo-sensitive area is situated adjacent to the respiratory rhythm centre which is highly sensitive to `CO_2` and `H^+`. Increase in these substances can activate this centre, which inturn can send signals to the respiratory rhythm centre to make necessary adjustments in the respiratory process by which these substances can be eliminated.
4. Receptors associated with aortic arch and carotid artery also recognize changes in `CO_2` and `H^+` concentration and send necessary signals to the respiratory rhythm centre for necessary actions.
The role of oxygen in the regulation of the respiratory rhythm is quite insignificant.
