Explain the mechanics of lung breathing
WebThe respiratory muscles displace the equilibrium of elastic forces in the lung and chest in one direction or the other by adding muscular contraction. During inspiration, muscle contraction is added to the outward elastic force of the chest to increase … WebMar 3, 2024 · After the oxygen and carbon dioxide trade places in the alveoli, the diaphragm relaxes and positive pressure is restored to the chest cavity. This forces the used air out …
