WebJun 16, 2024 · Gas 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 9.2. 6 ). The main function of the trachea is to funnel the inhaled air to the lungs and the exhaled air back out of the body. WebThe majority of marine gastropods breathe through a single gill, supplied with oxygen by a current of water through the mantle cavity. This current is U-shaped, so that it also flushes waste products away from the anus, which is located above the animal's head, and would otherwise cause a problem with fouling. binding of isaac laser eyeWebGills are thin tissue filaments that are highly branched and folded.
