Adaptations of the fish gas exchange system include high surface area (filaments and lamellae), rich blood supply, thin layers, overlapping tips of adjacent gill filaments for increased water contact time, and a countercurrent exchange system.
Las adaptaciones del sistema de intercambio gaseoso de los peces incluyen alta superficie (filamentos y lamelas), rico suministro de sangre, capas delgadas, puntas superpuestas de filamentos adyacentes para aumentar el tiempo de contacto con el agua y el sistema de intercambio a contracorriente.
