What do gills look like?

During Questions Week at Irchester the children have been finding out the answer to some of their questions. Sam had been studying habitats and how animals adapt to their environment and asked “What do gills actually look like?”

So, Sam and some other Year 4 students  came to Lab_13 to find out.  They dissected fish to examine all the different body parts that make the fish suitable for living in water. The swim bladder is an organ which helps the fish with buoyancy and we were excited to find it and feel it. Then we explored the other organs and were surprised to find the fish’s heart is very close to the back of his head almost in between the gills

??????????Then, it was time to extract the gills to see what they look like and how they work.  We were amazed by how pretty they actually were. The gill filaments look like long feathery parts at the top and the gill arches were the roundy half moon pieces that attached the filaments to the inside of the fish. Then there were the gill rakes at the bottom. It was a very interesting way to answer Sam’s question!
