WebJun 16, 2024 · The bronchioles branch into bronchi. Alveolar ducts connect to alveolar sacs. 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 ). WebJun 10, 2024 · The gills are a fish’s gas exchange system. The fish opens its mouth to let water in, then closes its mouth and forces the water through the gills and out through the operculum (gill cover). This means the water flows through the gills in one direction, allowing for more efficient gas exchange than if the water had to go in and out the same ...
WebCounter-Current Exchange. In reality the blood flowing through lamellae travels in the opposite direction to the water passing over the gills. This ensures that a concentration gradient is maintained across the entire gas exchange surface. Oxygen deficient blood entering the gills is exposed to oxygen poor water that is about to leave the gills ...
