Carbon dioxide and blood PH
Carbon dioxide and blood pH modify reparatory rate and depth.
The three characteristics of a respiratory rate are rate, depth, and rhythm.
Respiratory control centers are located in the medulla and the pons. In the medulla the ventral respiratory group contains rhythm generators whose output drives respiration. Also in the medulla, the neurons of the dorsal respiratory group integrate peripheral sensory input and modify the rhythms generated by the VRG. The pons respiratory centers interact with the medulla centers to smooth the breathing pattern. The respiratory center (RC), itself, is located in the medulla oblongata, the lowermost portion of the brainstem.
Several factors can affect respiratory rate and depth. Two of these are strong emotions, as well as pain acting through the limbic system, which activate sympathetic centers in the hypothalamus. Other factors are fever, labor, fear, anger, happiness, running, sleeping, yoga , meditation, and conditions like high BP or Low BP.
chemical factors in the blood
yes
The higher the respiratory rate and deeper the breaths the lower the blood CO2.
Yes, changes in arterial pH can modify respiration rate and rhythm through the peripheral chemoreceptors, even when carbon dioxide and oxygen levels are normal. This is known as respiratory compensation and helps maintain acid-base balance in the body by adjusting the rate and depth of breathing.
Chemical factors, such as levels of carbon dioxide (CO2), oxygen (O2), and pH in the blood, significantly influence breathing patterns. Increased CO2 levels or decreased O2 levels stimulate chemoreceptors that signal the respiratory center in the brain to increase the rate and depth of breathing, enhancing gas exchange. Conversely, a rise in blood pH (alkalosis) may slow respiration, while a drop (acidosis) typically accelerates it. These adjustments help maintain homeostasis and ensure that the body's metabolic needs are met.
Carbon dioxide
Yes. The hypothalamus is part of your autonomic nervous center and can influence rate and depth in response to pain and temperature changes
Respiratory exertion refers to the increased effort required for breathing during physical activity or due to certain medical conditions. It often involves a rise in the rate and depth of breathing as the body demands more oxygen and needs to expel carbon dioxide. Factors such as exercise intensity, altitude, and respiratory health can influence the level of exertion experienced. Individuals with respiratory issues may experience pronounced exertion even with minimal activity.
