The diaphragm regulates respiration - so both inhalation and exhalation. I reccomend this nt be placed in radiology as it is at the time of this writing.
The Diaphragm.
The diaphragm, a sheet of muscles spanning the rib cage just below the lungs, is mainly responsible for both inspiration and expiration. The intercostal muscles are also used, expanding and contracting the the space between the ribs. The abdominal muscles are used to a lesser extent either by relaxing to allow further expansion of the diaphragm or contraction for rapid expulsion of air. (Note to the person who answered this question previously: "Inspiration" means to inhale. "Expiration means to exhale. Don't tell someone that they don't know what they are talking about unless you know what you are talking about.)
Normal inspiration and expiration is directly related to contraction and relaxation of the diaphragm. This is involuntary act, normally.
Inspiration & expiration
pontine respiratory group (PRG)
They assist the diaphragm with inspiration and expiration.

Interval between expiration and inspiration
Breathing. These muscles are used to change the pressure in the chest so air can flow in and out of the lungs (on inspiration and expiration).

The Diaphragm.
Muscles of inspiration include: diaphragm, scalenes, pectoralis minor, and external intercostals. The muscles of expiration include: abdominals and internal intercostals.
Inspiration should equal to expiration;IE ratio and IT , inspiration equals tidal volume. It means that the patient is having trouble breathing.
Yes, in asthma, bronchitis, emphysema expiration is difficult than inspiration..
Inspiration is due to the contraction of the diaphragm and external intercostal muscles.
The diaphragm contracts, causing the lungs to expand. This creates a 'pressure difference' and air fills the lungs. When the diaphragm relaxes, it 'squeezes'[ the lungs, forcing the unabsorbed air (and waste gasses) back out again.
Mainly the diaphragm.
