Dogfish gill. Light micrograph of a gill ray and gill lamellae,from a dogfish (Scyliorhinus canicular). This section through the gill shows parts of its cartilaginous support structure. Across top is the gill arch and the gill rays,while the pharyngeal wall is across centre. Colours of tissues are: epidermis (purple),muscles (red),blood cells (purple-black). Cut lengthwise across bottom are the afferent and efferent brachial arteries taking blood to and from the gills. Gills are used by fish to breathe underwater,to extract oxygen from the water,and to dispose of waste carbon dioxide. Magnification: x36 when printed at 10 centimetres across | |
