The diaphragm is the major muscle of the respiratory system.
The main ones are the diaphragm, external and internal intercostals.
Inspiratory muscles involve respiration (breathing). The diaphragm, chest muscles, lungs, are all in the inspiratory system.
The diaphragm
The deep muscles of the thorax that promote inhaling are known as the diaphragm muscles. These are the muscles that are activated when a person has good posture and takes a deep breath.
The deep thorax muscles are the deep muscles of the thorax that promotes the inspiratory phase of breathing. When breathing the diaphragm contracts, producing a negative pressure, which forces are into the lungs.
wheeze can be inspiratory or expiratory but stridor is mostly inspiratory
The amount of O2 inspired would be the same as CO2 expired only if the individual were burning strictly carbohydrates (1:1 respiratory coefficient). Respiratory coefficient= CO2 eliminated per O2 consumed. Because animals also burn fats and proteins, there is no longer a 1:1 ratio because these energy sources have greater O2 consumption vs CO2 production (0.7:1 for fats). Therefore, the decreased CO2 production will cause the expiratory V to be less than the inspiratory V.
Inspiratory reserve volume is the volume you can inhale past the normal tidal volume.
time-cycled = inspiratory phase ends when the preset inspiratory time is reached flow-cycled = inspiratory phase ends when the preset flow rate is reached
ACUTE EFFECT - The inspiratory and expiratory volume decreases during exercise
inspiratory reserve volume= expiratory reserve volume + Tidal Volume - Vital capacity
when you breath in and out up and down
Did you mean reserve volume?
stridor
Expiraroty dyspnea (remember all pulmonary diseases have expiratory or mixed dyspneas and heart diseases are differentiated by inspiratory dyspneas)
