Web30 mrt. 2024 · Explain 2 ways in which the structure of fish gills is adapted for efficient gas exchange. This system maximises the amount of oxygen diffusinginto the blood by having the most oxygenated blood meet the most oxygenated water, and the least oxygenated blood meet the least oxygenated water. Web13 feb. 2014 · Most sharks have five pairs of gills made up of cartilaginous gill arches that support a vast network of gill filaments. These filaments are highly vascularised, meaning they contain numerous thin blood vessels and provides a large surface area for gas exchange. This also explains the bright red coloration found in shark (and fish) gills.
