It can be entirely passive, since the lungs expel air as they deflate. However, voluntarily breathing out forcefully is part of some exercises, using the abdominal muscles to push the diaphragm upward.
Active Exhalation a.k.a. Forced Expiration - Accessory muscles are used to assist passive forces Accessory muscles used: INTERNAL RIB CAGE MUSCLES- 1. Internal Intercostals 2. Transversus Thoracis 3. Subcostals EXTERNAL RIB CAGE MUSCLES- 1.Serratus Posterior Inferior 2.Quadratus Lomborum ABDOMINAL MUSCLES- 1. Rectus Abdominis 2. External Oblique 3. Internal Oblique 4. Transversus Abdominis Hope this helps :D
Passive (diffusion).
Passive
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Passive
The primary muscle used in active expiration is the diaphragm (it relaxes from its contracted state to decrease the volume in the lungs, forcing air out). Internal intercostals, the interosseous portion, will assist by pulling the rib cage down.
Active - as it involves the contraction of muscles.
Passive means passive - no muscle action is necessary. You must use your muscles to inhale ... and you can use them to speed up exhalation.
OInhalation is a process that relies on contraction of muscles while exhalation is a process that is USUALLY-not always-passive because it relies on the relaxation of muscles. However, when you speak, sing, or blow out a candle the muscles between the ribs and abs contract, making it active.
inspirationInpiration involves contraction of muscles. This is an energy requiring process
