The diaphragm & the external intercostal muscles (the muscles between the ribs that course downward) are the two most important muscles of inhalation, but there are many other muscles that also contribute to this process.
Other muscles of inhalation include:
-Pectoralis major
-Pectoralis minor
-Serratus anterior
-Costal levators
-Subclavius
-Serratus posterior superior
-Serratus posterior inferior
Inhalation, exhalation
Inhalation means breathing in, and exhalation is breathing out.
Passive means passive - no muscle action is necessary. You must use your muscles to inhale ... and you can use them to speed up exhalation.
Both inhalation and exhalation are part of the respiratory process where air is exchanged in the lungs. During inhalation, the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. During exhalation, these muscles relax, and the chest cavity decreases in size, forcing air out of the lungs. The key difference is the direction of airflow: inhalation is the process of taking air into the lungs, while exhalation is the process of expelling air from the lungs.

Inhalation
Inhalation means breathing in, and exhalation is breathing out.
Inhalation is an active process and exhalation is a passive process
Inhalation is caused by the diaphragm and external intercostal muscles contracting, which increases the volume of the chest cavity. Exhalation is primarily a passive process, where the diaphragm and external intercostal muscles relax, allowing the chest cavity to decrease in volume and air to be expelled from the lungs.
The intercostal muscles, (muscles between the ribs), contract.
