Question

Что происходит с мышцами живота при вдохе? при выдохе?

Answer 1

What happens to the abdominal muscles during inhalation?

During inhalation, the abdominal muscles play a role in the expansion of the chest cavity and the diaphragm. The diaphragm, a dome-shaped muscle located at the base of the lungs, contracts and moves downward, causing the chest cavity to expand. This expansion creates negative pressure within the lungs, allowing air to be drawn in. At the same time, the abdominal muscles relax and move outward, allowing the diaphragm to descend more easily and further increase the volume of the chest cavity. This coordinated action of the diaphragm and abdominal muscles helps facilitate the process of inhalation.

What happens to the abdominal muscles during exhalation?

During exhalation, the abdominal muscles contract to assist in the expulsion of air from the lungs. The contraction of the abdominal muscles increases the pressure in the abdominal cavity, which pushes the diaphragm upward. This upward movement of the diaphragm reduces the volume of the chest cavity, causing air to be forced out of the lungs. The contraction of the abdominal muscles also helps to compress the abdominal organs, aiding in the expulsion of air during exhalation.

In summary, during inhalation, the abdominal muscles relax and move outward, while during exhalation, they contract and move inward.
