Which two chemical factors can modify respiratory rate and depth?
Carbon dioxide and blood PH
What are 3 characteristics of a respiratory surface?
The three characteristics of a respiratory rate are rate, depth, and rhythm.
What is a respiratory control center?
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.
What are factors that influence the rate and depth of breathing?
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.
What are the factors which control respiration?
chemical factors in the blood
Does stimulation of chemoreceptors cause a decrease in respiratory rate and depth?
yes
What is the relationship between increased blood co2 and respiratory rate and depth?
The higher the respiratory rate and deeper the breaths the lower the blood CO2.
Can changes in arterial pH modify respiration rate and rhythm even when carbon dioxide and oxygen levels are normal?
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.
What is the strongest stimulus to increase respiratory rate and depth is to increase the blood concentration of?
Carbon dioxide
Can the hypothalamus influence respiratory rate and depth?
Yes. The hypothalamus is part of your autonomic nervous center and can influence rate and depth in response to pain and temperature changes
Where in body is the respiratory center located?
it's your lungs
How does soil vary from depth?
Soil properties can vary with depth due to factors like organic matter content, texture, nutrient levels, and pH. Generally, surface soil layers (topsoil) tend to have more organic matter and nutrients, while deeper layers may have different physical and chemical characteristics based on factors like weathering processes and root activity. The depth of the soil profile can also affect water retention, nutrient availability, and root growth.
