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 main difference between the muscles involved in inspiration and expiration is that inspiration involves the diaphragm and external intercostal muscles, which contract to expand the chest cavity and draw air into the lungs. In contrast, expiration primarily involves the relaxation of these muscles, along with the internal intercostal muscles and abdominal muscles, which contract to compress the chest cavity and push air out of the lungs.
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.)
The diaphragm is the prime mover of inspiration, as it contracts and flattens during inhalation, creating a vacuum in the chest cavity that allows air to be drawn into the lungs.
Normal inspiration and expiration is directly related to contraction and relaxation of the diaphragm. This is involuntary act, normally.
The process of smoothing transitions from inspiration to expiration is regulated by the respiratory centers in the brainstem, which coordinate the contraction of respiratory muscles. This includes the diaphragm and intercostal muscles, which work together to control the flow of air in and out of the lungs. Smooth transitions are important for maintaining a regular breathing pattern and efficient gas exchange in the body.
They assist the diaphragm with inspiration and expiration.
The end of inspiration is signalled by the relaxation of the diaphragm and the external intercostal muscles. This causes the lungs to passively recoil, leading to expiration.
During inspiration, the diaphragm and intercostal muscles contract, expanding the chest cavity and allowing air to rush into the lungs. During expiration, the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and air to be pushed out of the lungs.
Normal inspiration and expiration is directly related to contraction and relaxation of the diaphragm. This is involuntary act, normally.
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).

Expired means past use or dead. Inspired (inspire) means to be enlivened or filled with exalting emotion.
During normal breathing at rest, inspiration is an active process while expiration is passive. So under normal conditions, you put more energy into inspiration than expiration.
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.
