Gas Exchange in Fish Tutorial. AS Biology WJEC EDUQAS

In this video I cover gas exchange in fish. I explain the structure of the gills of a bony fish, this includes: • Gill filaments • Gill lamellae • Gill rakers • Afferent and efferent arterioles. I also explain the counter-current flow and the parallel flow of gas exchange in bony and cartilaginous fish. I address several questions at the end of the video. ----------------- This video will help students on all UK exam boards: AQA, OCR, EDEXCEL, WJEC, EDUQAS, EDEXCEL International and Cambridge International. ----------------- If you want help with a particular topic – for any exam board – please let me know.
