Today, the girls were interested in what the liver does....so we read about the liver, and other organs, such as kidney, heart, and lungs....and played with the BBC's Interactive Body. From there, we also learned about some of the bones, and muscles.
Georgia told me about the organs in sharks and crocodilians, and how they differ from ours. She also talked about their sixth senses...how sharks use their Ampullae of Lorenzini, electroreceptors for detecting electric fields in the water, which living things give off when they use their muscles, and also how they can use the earth's magnetic field as their own mapping system....And she told us how crocs use their Dermal Pressure Receptors for detecting changes in pressure, making finding prey in the dark easier. That would be neat to have, huh?
We also talked about organ transplants.
