hingamisliigutuste

Hingamisliigutused refer to the physical actions involved in breathing. This encompasses the coordinated movements of the chest, diaphragm, and abdominal muscles that facilitate the intake and expulsion of air. Inhalation, the process of drawing air into the lungs, is an active phase primarily driven by the contraction of the diaphragm, a dome-shaped muscle located at the base of the chest cavity. As the diaphragm contracts and flattens, it increases the volume of the thoracic cavity, creating a negative pressure that draws air into the lungs. Simultaneously, the intercostal muscles between the ribs contract, lifting the rib cage and further expanding the chest.

Exhalation, the expulsion of air from the lungs, is typically a passive process at rest. When the diaphragm and intercostal muscles relax, the elastic recoil of the lungs and chest wall causes the thoracic cavity to decrease in volume. This reduction in volume increases the pressure within the lungs, forcing air out. During more forceful exhalation, such as during exercise or coughing, accessory muscles in the abdomen and neck become involved to actively contract and reduce the thoracic volume more rapidly. The efficiency and mechanics of these hingamisliigutused are crucial for maintaining adequate oxygen levels and removing carbon dioxide from the body. Variations in breathing patterns and the muscle groups primarily utilized can be observed in different physiological states and activities.
