Control Of Respiration
Control of ventilation refers to the physiological mechanisms involved in the control of physiologic ventilation. Gas exchange primarily controls the rate of respiration.
The most important function of breathing is gas exchange (of oxygen and carbon dioxide). Thus the control of respiration is centered primarily on how well this is achieved by the lungs.
There are four main centers in the brain to regulate the respiration: 1. Inspiratory center 2. Expiratory center 3. Pneumotaxic center 4. Apneustic center The first two centers are present on the medulla oblongata whereas the last two centers on the pons region of brain.

Famous quotes containing the words control of and/or control:
“The glance is natural magic. The mysterious communication established across a house between two entire strangers, moves all the springs of wonder. The communication by the glance is in the greatest part not subject to the control of the will. It is the bodily symbol of identity with nature. We look into the eyes to know if this other form is another self, and the eyes will not lie, but make a faithful confession what inhabitant is there.”
—Ralph Waldo Emerson (18031882)
“The child knows only that he engages in play because it is enjoyable. He isnt aware of his need to playa need which has its source in the pressure of unsolved problems. Nor does he know that his pleasure in playing comes from a deep sense of well-being that is the direct result of feeling in control of things, in contrast to the rest of his life, which is managed by his parents or other adults.”
—Bruno Bettelheim (20th century)
