Diaphragm
The diaphragm muscle.
Yes, a pulled chest muscle can cause pain when breathing due to the movement of the ribcage and the strain on the muscle during inhalation and exhalation.
The intercostal muscles, (muscles between the ribs), contract.
The inhalation phase. During the inhalation phase, the diaphragm contracts and this requires energy expenditure. The exhalation phase, on the other hand, only involves passive muscle recoil of the diaphragm and does not require work or energy.
Inhalation requires the contraction of the diaphragm, which takes ATP. Exhalation is simply the passive relaxation of that muscle, in which the atmospheric pressure causes the lung to deflate, taking no ATP.
When the lungs are expanded, this action takes place due to the diaphragm contracting during inhalation. During exhalation, the diaphragm relaxes.
Passive means passive - no muscle action is necessary. You must use your muscles to inhale ... and you can use them to speed up exhalation.
exhalation because the diaphragm (muscle that helps you breathe) wont function nor your lungs, therefore you can't breathe when you are dead
Ribs are bones, but lungs contribute to breathing and they are a muscle organNo, your Lungs ARE NOT A MUSCLE. Your diaphragm is the main muscle in inhalation, which opens your lungs (works by creating a negative pressure in your lungs i.e. the pressure outside your chest cavity is more than the pressure in your lungs, causing air to enter your lungs).However, during forced inhalation and exhalation your intercostal muscles and rectus abdominus muslces play a part in exhalation (forcing air out). scalenes lift up your rib cage to allow maximum inhalation.

The diaphragm is the main breathing muscle in your body. It is a dome-shaped muscle located at the base of the lungs that contracts and expands to help with the inhalation and exhalation of air.
The primary muscle that aids breathing in a pig is the diaphragm. This dome-shaped muscle separates the thoracic cavity from the abdominal cavity and plays a crucial role in respiration by contracting and relaxing to facilitate the inhalation and exhalation of air. When the diaphragm contracts, it moves downward, creating a vacuum that pulls air into the lungs. During exhalation, the diaphragm relaxes, pushing air out of the lungs.
