WebHow gas exchange occurs at the gills? Water taken in continuously through the mouth passes backward between the gill bars and over the gill filaments, where the exchange of gases takes place. The blood capillaries in the gill filaments are close to the gill surface to take up oxygen from the water and to give up excess carbon dioxide to the water. WebThe moving blood and ventilated gill surfaces mean that gases exchanged are continually removed – oxygen enters the blood, and carbon dioxide removed to the water. High …
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.
