What chemical factors control the rate and depth of respiration?
Chemical- carbon dioxide, hydrogen ions and oxygen levels are the most important factors that regulate respiration.
What are at least two things that can affect breathing rate or depth of breath?
although many factors can modify respiratory rate and depth, the most important factors are chemical – the levels of carbon dioxide and oxygen in the blood. Increased levels of carbon dioxide and decreased blood pH are the most important stimuli leading to an increase in the rate and depth of breathing.
What factors impact respiratory rate?
There are various factors that affect a person’s breathing rate, including injuries, exercise, emotion, mood, as well as a range of medical conditions.
What are the 4 physical factors that can affect the respiratory rate?
The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.
What are two factors that can affect respiratory rate?
The most common factors that can affect your measured respiratory rate include:
- emotional state.
- physical fitness.
- internal temperature.
- disease and health status.
What is the chemical control of respiration?
The chemical regulation of respiration concerns the hydrogen ion content of the respiratory neurones which in turn is dependent upon the carbon dioxide tension of the blood and the rate of flow of blood through the medulla.
What chemical factor is most important in modifying respiratory rate and depth?
Chemical Factors Respiratory rate and depth can be altered by chemical factors such as levels of carbon dioxide and oxygen in the blood. The most important stimuli are increased levels of carbon dioxide and decreased blood pH that act on the medulla centers of the brain, increasing respiration rate.
How do you increase respiratory rate?
To keep your lungs healthy, do the following:
- Stop smoking, and avoid secondhand smoke or environmental irritants.
- Eat foods rich in antioxidants.
- Get vaccinations like the flu vaccine and the pneumonia vaccine.
- Exercise more frequently, which can help your lungs function properly.
- Improve indoor air quality.
What factors influence the rate of respiratory quizlet?

What factors affect the respiration rate of yeast?
The rate of respiration is influenced by different factors(e.g. temperature, pH, nutrient availability). The effect of each of these factors can be determined by changing one variable only, and observing its effect on the rate of reaction.
What are the chemical signals that trigger increased respiration?
Sources of these signals include mechanoreceptors in the exercising limbs; the arterial chemoreceptors, which can sense breath-by-breath oscillations in the partial pressure of carbon dioxide; and thermal receptors, because body temperature rises as metabolism increases.
What are chemical regulators?
In chemical regulation, substances called hormones are produced by well-defined groups of cells and are either diffused or carried by the blood to other areas of the body where they act on target cells and influence metabolism or induce synthesis of other substances.
What happens when the volume of the lungs increases?
Explain exactly what happens, in terms volume and pressure changes in the lungs, when these muscles contract. Muscular contractions increase volume of the throax, the increase in volume causes a decrease in pressure, air flows from higher pressure to lower pressure until the pressure becomes equal.
How are non respiratory movements different from normal breathing?
Name several nonrespiratory air movements, and explain how each differs from normal breathing. Coughing, sneezing, laughing, crying, and yawning. They’re non respiratory movements because the process, there is no exchange of gases involved.
What causes air to flow out of the lungs during expiration?
Muscular contractions increase volume of the throax, the increase in volume causes a decrease in pressure, air flows from higher pressure to lower pressure until the pressure becomes equal. what causes air to flow out of the lungs during expiration?
What makes the alveoli ideal for gas diffusion?
The alveoli consist of one layer of simple squamous cells so they are very thin. The thinness makes the diffusion of gases ideal. What does TV, ERV, and VC mean?
