The diaphragm can be forced to move higher than normal by contraction of the accessory muscles such as the intercostal muscles, scalene muscles, and neck muscles during increased respiratory demands or strenuous breathing activities. These muscles help to expand the chest cavity further, allowing for increased lung capacity and deeper breaths.
An abdominal wall is the layer of muscles which surrounds the abdominal cavity and contains the abdominal organs.
Proper control of the respiratory passages depends upon the coordination of muscles in the diaphragm, intercostal muscles, and other accessory respiratory muscles. Additionally, the autonomic nervous system plays a key role in regulating the dilation and constriction of the airways through the action of the sympathetic and parasympathetic nerves. This control ensures the optimal exchange of oxygen and carbon dioxide in the lungs.
There are the abdominal muscles and the oblique's. They help to keep you standing straight and when working properly, your back healthy.
Hypercapnia, increased levels of carbon dioxide in the blood, stimulates ventilation by acting as a powerful stimulus to breathe. Chemoreceptors in the brainstem sense the high carbon dioxide levels and signal the respiratory muscles to increase ventilation rate and depth. This helps to remove excess carbon dioxide from the body and restore normal levels of blood gases.

Use of accessory muscles on inspiration (e.g., in patients with COPD, asthma, thoracic scoliosis, and ankylosing spondylitis).
Muscles of Respiration: The main muscles of respiration are the Diaphragm, which forms the partition of the chest from the abdomen, and the abdominal muscles. Accessory muscles will also take part in helping with respiration during respiratory distress after severe exercise, respiratory obstruction, heart failure. The accessory muscles are, sternocleidomastoid, platysma, and the strap muscles of the neck.
abdominal muscles
I'm no expert but one difference is your external abdominal muscles are voluntary and intestinal muscles are involuntary.
Active exhalation is when the muscles of the diaphragm and other respiratory muscles contract to push air out of the lungs. This process helps to expel carbon dioxide and other waste gases from the body. It is a key part of the breathing cycle.
An abdominal wall is the layer of muscles which surrounds the abdominal cavity and contains the abdominal organs.
The average breathing for an adult is 12 to 20 breaths per minute. The act of breathing consists of two phases, inspiration and expiration.Early signs of respiratory distress include:- increased respiratory rate- flaring of the nostrils- use of accessory muscles of respiration
The accessory muscles of respiration are the sternocleidomastoid, scalenes, serratus anterior, pectoralis major and minor, upper trapezius, latissimus dorsi, erector spinae (thoracic), iliocostalis lumborum, quadratus lumborum, serratus posterior superior and inferior, levatores costarum, transversus thoracis, and subclavius. The diaphragm is the main muscle of respiration (normal/relaxed breathing), assisted by the intercostals. No accessory muscles should be recruited during normal respiration unless there is a respiratory disorder. During quiet inspiration, the diaphragm and intercostals are activated. During quiet expiration, the inspiratory muscles relax and the elastic recoil of the lung tissue combined with intrathoracic pressure causes air to be pushed out of the lungs. There is little or no respiratory activity of the abdominals. When increased oxygen is required during physical activity e.g. when running, accessory muscles will activate to assist forced respiration.
The causes of loose abdominal muscles include extreme weight loss and pregnancy.
I need to work on my abdominal muscles.
