Web2 jan. 2024 · Gas exchange surfaces are adapted to maintain a high rate of diffusion: they have a large surface area, are thin, and are ventilated to maintain high concentration gradients of oxygen and carbon dioxide. Ventilation happens due to changing volume and pressure (in the buccal cavity in fish). Web5 Mark s. Students investigated the effect of temperature on the breathing rate of fish. They put fish of the same size in tanks of water at different temperatures. They. measured the breathing rate by counting the number of times the fish opened. their mouths in a minute. The results are shown in the table. Water temperature in °C.

WebFish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx. Web24 dec. 2011 · Gills and lungs are the main tissues that provide gas-exchanging surfaces for the respiratory function of most of the higher animals. Primarily fish has gills while amphibians, reptiles, birds, and mammals have lungs for respiration or gas exchange.

WebThe 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 … WebFish and many other aquatic organisms have evolved gills to take up the dissolved oxygen from water ( Figure 20.4 ). Gills are thin tissue filaments that are highly branched and folded. When water passes over the gills, the dissolved oxygen in water rapidly diffuses across the gills into the bloodstream.
