How Do Sharks Breathe Gill Anatomy and Histology

In this video, we look at the structure of shark gills from the macroscopic down to individual cells. The anatomy is optimised to create the shortest distance, fractions of the width of a human hair, between water and blood to allow gas exchange. Even the position of cell nuclei is determined to achieve the right interface for gas exchange. • The slides used in this video can be accessed via the website at http://downthescope.co.uk : • 237 - http://downthescope.co.uk/histoslide/... • 241 - http://downthescope.co.uk/histoslide/... • 246 - http://downthescope.co.uk/histoslide/... • If you would like more information about shark and fish gills, their anatomy and function then check out these review papers: • Elasmobranch Gill Structure - Nicholas Wegner: https://www.researchgate.net/publicat... • The Multifunctional Fish Gill: Dominant Site of Gas Exchange, Osmoregulation, Acid-Base Regulation, and Excretion of Nitrogenous Waste - David H.
