Carbon dioxide
The greatest stimulation on the respiratory center in the brain comes from an increase in carbon dioxide levels in the blood. This triggers the respiratory center to increase breathing rate to eliminate excess carbon dioxide and restore normal levels of oxygen in the blood.
If the blood concentration of carbon dioxide increases, the breathing rate is most likely to increase. This occurs as a response to remove excess carbon dioxide from the body and maintain a balance of oxygen and carbon dioxide levels in the blood.
Carbon dioxide concentration helps maintain homeostasis by regulating pH levels in the blood. When carbon dioxide levels increase, the body responds by increasing breathing rate to remove excess carbon dioxide, which helps maintain a stable pH balance. Additionally, carbon dioxide is involved in the regulation of blood flow and plays a role in maintaining the acid-base balance in the body.
The most important chemical stimuli leading to an increased rate of breathing is an increase in carbon dioxide levels in the blood. This triggers the body's respiratory control system to stimulate the respiratory muscles to breathe more rapidly and deeply to remove excess carbon dioxide and restore normal blood gas levels.
The primary chemical stimulus used to control breathing is changes in the concentration of carbon dioxide in the blood. When carbon dioxide levels increase, it triggers an increase in breathing rate to remove excess carbon dioxide and restore balance.
If you hold your breath, the carbon dioxide concentration in the blood will increase. Carbon dioxide is constantly produced by the body's metabolism, and constantly exhaled. So if it is not exhaled, it will start to build up.
Exchange of both oxygen and carbon dioxide through the respiratory membrane occurs by diffusion. Oxygen moves from an area of high concentration in the alveoli to an area of low concentration in the blood, while carbon dioxide moves from high concentration in the blood to low concentration in the alveoli.
Increasing concentration of carbon dioxide in the atmosphere is considered a factor that increase the global warming.
The respiratory centers that control your rate of breathing are in the brainstem or medulla.Specialized nerve cells within the aorta and carotid arteries called peripheral chemoreceptors monitor the oxygen concentration of the blood and feed back on the respiratory centers.Peripheral chemoreceptors also monitor the carbon dioxide concentration in the blood. In addition, a central chemoreceptor in the medulla monitors the carbon dioxide concentration in the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord; carbon dioxide diffuses easily into the CSF from the blood. If the carbon dioxide concentration gets too high, then both types of chemoreceptors signal the respiratory centers to increase the rate and depth of breathingThe peripheral and central chemoreceptors are also sensitive to the pH of the blood and CSF.
