The … WebTracheal gas exchange continues after the beetle submerges and anchors beneath the surface. As oxygen is consumed from the bubble, the partial pressure of oxygen within the bubble falls below that in the water; consequently oxygen diffuses from the water into the bubble to replace that consumed. how to splice wires with solder https://bedefsports.com

Blood flows through the lamellae in one direction - and water flows in the opposite direction Q1. What is the name for this movement of blood and water? Q2. Explain why this system of movement is so important - in maximising gas exchange in fish. (3 key points) 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 ).
