Both aid in the expansion and relaxation of lungs.
The thoracic diaphragm, where its contraction assists inhalation and relaxation assists exhalation plays a main role in altering the lung's volume and air pressure inside, contributing to the process of respiration. Many other muscles are involved in both raising and lowering the ribcage, and any stomach muscles involved assist in exhalation.
The major function of the phrenic nerves is to innervate the diaphragm, which is the primary muscle responsible for respiration. These nerves play a crucial role in controlling the movement of the diaphragm during breathing by sending signals from the brain to the diaphragm muscle. Dysfunction of the phrenic nerves can lead to respiratory issues and difficulty breathing.
The diaphragm and intercostal muscles help in expanding and contracting the chest cavity to facilitate breathing. Additionally, the rib cage and lungs also play a role in assisting in respiration.
the diaphragm play an important role in breathing. hope it helped....
The muscle that plays the main role is the diaphragm.:)
Both the sheep diaphragm and human diaphragm are dome-shaped muscles located beneath the lungs that help with breathing. They contract and relax to create negative pressure in the thoracic cavity, allowing air to enter the lungs. Both diaphragms also play a role in assisting with other bodily functions such as coughing and sneezing.
Diaphragm.
There is no organ responsible for protecting the lungs (one may argue the skin), but the ribcage plays a large (if not the largest) role in protecting the lungs.The diaphragm is the primary muscle for breathing and the intercostal muscles (between ribs) are secondary respiratory muscles.
The diaphragm belongs to the Muscular and Respiratory systems.RespiratoryThe diaphragm is part of the respiratory system.The diaphragm is a large, dome-shaped muscle that plays an important role in breathing. Therefore, even though it helps out with breathing, it is a part of the muscular system.

The diaphragm is a dome-shaped muscle located below the lungs that plays a crucial role in breathing. When you inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and fill with air. This action allows you to take in oxygen. When you exhale, the diaphragm relaxes and moves back up, pushing air out of the lungs. In summary, the diaphragm helps regulate the process of breathing by controlling the volume of air in the lungs.
During inspiration, the primary muscles involved are the diaphragm and intercostal muscles. Muscles not involved in this process include the abdominal muscles and certain back muscles, such as the latissimus dorsi, which primarily assist with other movements rather than inhalation. Additionally, while accessory muscles like the sternocleidomastoid and scalene muscles may aid in deep or labored breathing, they are not required for normal inspiration. Thus, many core and upper body muscles do not play a direct role in the act of inhaling.
