13 Questions
What is the primary function of respiratory regulation?
To maintain the appropriate levels of O2 delivery and CO2 removal
Where is the Respiratory Control Centre (RCC) located?
In the medulla oblongata
What is the role of the Inspiratory Centre (IC) during rest and exercise?
To stimulate inspiratory muscles
What nerve is responsible for stimulating the diaphragm during rest?
Phrenic nerve
What type of receptors are responsible for detecting changes in O2 and CO2 levels during exercise?
Chemoreceptors
What is the role of the Expiratory Centre (EC) during exercise?
To stimulate additional expiratory muscles
What happens to the diaphragm during inhalation during exercise?
It flattens
Which muscle is stimulated during inhalation during exercise?
Sternocleidomastoid, pectoralis minor, and scalenes
What is the role of the RCC during exercise?
To coordinate the respiratory response to exercise
what are the first two stages of the respiratory cycle.
the respiratory control centre (RCC) stimulates the inspiratory centre to coordinate the rhythmic cycle of breathing
What is the primary stimulus that triggers the regulation of respiratory rhythm?
Changes in CO2 levels in the blood
what are the final two stages of the respiration regulation cycle at rest?
the nerve impulses stimulate the inspiratory muscles, these include the intercostal nerve (ext intercostals) and the phrenic nerve (diagphram)
what is the process of the respiratory regulation system for inspiration during exercise?
chemo, thermo and proprioceptors detect changes in the body that occur when a person will exercise, this will be coordinated by the RCC which will send an impulse to the inspiratory centre stimulating: Diphragm flattens, external intercostals, sternocleidomastoid, pectoralis minor & scalenes contract.
Learn about the system that regulates breathing rate, tidal volume, and minute ventilation to maintain optimal O2 delivery and CO2 removal during exercise and other physiological changes.
