Breathing Skin

Cutaneous respiration is the process of release of carbon dioxide from the alveoli through the capillaries into the alveolar air as a result of physical activity. Despite the name, cutaneous gas exchange affects not only breathing, but also cardiac activity. Under resting conditions, the alveoli do not experience compression or changes in configuration. To maintain immobility, the alveoli require normal external pressure, and for its proper circulation, the functions of the cutaneous circulatory system are necessary. Compression of the lungs during exhalation is carried out due to vibrations of the walls of the alveoli and the movement of the diaphragm when the muscle contracts as the volume of air above it decreases. When the alveolus expands during inspiration by passive antiperistalsis, the alveolar walls usually do not reduce pressure in the pulmonary circulation. However, very often at rest the lung rises due to the diaphragm and clavicles; and gases (CO2 and O2) move below the lung into the atmosphere. With severely shortened breathing, the increase in lung volume caused by the expansion of the alveoli during exhalation is less noticeable, which leads to a decrease in the degree of stretching
