What centers regulate the work of the respiratory system? How is respiration regulated?

Nervous regulation is carried out thanks to the respiratory center located in the medulla oblongata. One group of nerve cells in the respiratory center is responsible for inhalation – this group is called the inhalation center. Another group – the center of exhalation – is responsible for exhalation. Moreover, inhalation and exhalation reflexively stimulate each other. The nerve cells responsible for inhalation are connected through the spinal cord to those muscles that raise the ribs and lower the diaphragm. After that, the neurons of the exhalation center come into action. A person is able to arbitrarily hold, reduce or speed up breathing, change its depth. This is possible because the activity of the respiratory center of the medulla oblongata is under the control of the higher parts of the brain.
