How do tracheae facilitate gas exchange
WebDec 19, 2024 · You've just used your respiratory system to exchange gasses in your body. You breathed in air, which contains oxygen, and that oxygen is used for numerous cellular processes in your body. WebGas exchange between the lung and blood takes place in the alveolus. From the nasal cavity, air passes through the pharynx (throat) and the larynx (voice box), as it makes its way to the trachea ( Figure ). The main function of the trachea is to funnel the inhaled air to the lungs and the exhaled air back out of the body.
