WebIn terms of the adaptions fish have to maximise gas exchange, 1. 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) WebSometimes, book lungs can be absent, and gas exchange is performed by the thin walls inside the cavity instead, with their surface area increased by branching into the body as thin tubes called tracheae. WebSep 8, 2024 · How does an insect help in gas exchange? Insects use rhythmic abdominal movements to move air in and out of the spiracles. This helps to remove the carbon dioxide from the body and get oxygen into the tracheae for gas exchange. Finally, fish use gills and lamellae. Gills use a counter-current system.

Gases move by diffusion within the tracheal system. When the insect is less active the ends of the tracheoles contain fluid. It is where the fluid and gas meet (= the fluid/gas interface), that exchange of gases occurs (oxygen is taken up, carbon dioxide is given off).

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. WebApr 9, 2024 · Animal respiratory systems are designed to facilitate gas exchange. In mammals, air is warmed and humidified in the nasal cavity.
