medullary respiratory centers
The three characteristics of a respiratory rate are rate, depth, and rhythm.
medulla oblongata
Hyperventilation occurs when the respiratory system is not functioning properly. Hyperventilation is when the breathing rhythm is not proper, shorter breathes, and too much carbon dioxide becomes present.
The answer is Ventral Respiratory Group or VRGIt contains the rhythm generators "whose output drives respiration".Hoehn, Marieb Human Anatomy & PhysiologyEighth Edition pg. 835

medulla and pons
The- respiratory group within the madulla oblongata regulates the basic rhythm of breathing.
The basic rhythm of breathing is controlled by part of the brain called the Medulla.
the medulla oblongata
Ventilatory rhythm is the regular pattern of breathing that involves the inhalation and exhalation of air to exchange oxygen and carbon dioxide in the body. It is controlled by the respiratory centers in the brainstem and is influenced by factors such as CO2 levels, oxygen levels, and metabolic demand. Changes in the ventilatory rhythm can occur in response to exercise, emotions, or certain medical conditions.
