What happens to the respiratory system during inspiration?
During inspiration, muscle contraction is added to the outward elastic force of the chest to increase the traction on the lung required for its additional stretch. When these muscles relax, the additional retraction of lung returns the system to its equilibrium position.
Where does the rhythmicity of breathing take place?
1.the medullary rhythmicity centre, controlling the basic rhythm of ventilation and made up of an inspiratory centre and expiratory centre, located i the medulla oblongta 2.the apneustic area, located in the pons, capable of activating the inspiratory system and prolonging its action.
How does the expansion of the thorax affect breathing?
This expansion means there is an increase in the volume of the thorax and a decrease in intrapulmonary pressure. A pressure gradient is therefore established from the atmosphere to alveoli, hence air being suck into the lower pressure in the lungs called inspiration or breathing in. NEW! AI matching with writer
How is the flow of air related to the mechanism of breathing?
The flow rate of air is in proportion to the magnitude of the pressure difference. The breathing mechanism involves two processes: In the process of inspiration, there would be a contraction of muscles attached to the ribs on the outer side which pulls out the ribs and results in the expansion of the chest cavity.
