31 sie 2023 · Breathing is one of the four components of respiration, the other three being gas diffusion, gas transport and regulation. The pathway towards the lungs is provided by airways and together, these components form the respiratory system, which is located inside the thoracic or chest cavity.
31 paź 2023 · During exhalation, the diaphragm also relaxes, moving higher into the thoracic cavity. This increases the pressure within the thoracic cavity relative to the environment. Air rushes out of the lungs due to the pressure gradient between the thoracic cavity and the atmosphere.
