[Mitochondrial respiration and oxygen transport during various stages of lung inflammation]
Abstract:
It is shown in rats with experimental lung inflammation that the phosphorylative and uncoupling mitochondrial respiration intensity rises at acute and reverses to the normal level at subacute inflammation. At chronic inflammation the 2,4-DNP-stimulated mitochondrial respiration enhances and the ADPO coefficient lowers. At all stages of inflammation the pO2 rise in muscles after O2-inhalation is less than in healthy animals. The disturbance of O2 transport in organism may be the reason of the described low energy shift at lung inflammation.

Factors Affecting Respiration
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
Respiration and Gaseous Exchange
Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves the...
