The brain. There’s so little we understand about it, like how can what is essentially a enormous number of switches (like the biggest computer ever) be capable of conscious thought. And if that’s the case, if you built a computer big enough, would it start to think for itself? These are themes that people in artificial intelligence are seriously thinking about.
The liver is my favourite organ. Under the microscope the human liver doesn’t look very interesting, but its role is really cool. The liver is mainly responsible for making compounds less toxic by making them more hydrophilic (water soluble) so that they can be safely excreted from the body in the urine. But, the liver can also make compounds more toxic which isn’t good. In pigs, the structure of the liver is beautiful; it looks like lots of hexagons. Funny, how the same organ can look so different but do the same job!
I think the eye, or the part of the brain which deals with sight. I think how the brain can take the information which the eye gives it, which is three colours only plus brightness, and the image is flipped around, and turn that into a working image, is fascinating. The more you look into it, the more it baffles me – I learnt the other day that the colour purple was just made up by your brain?! People have had digital implants into their eyes to help blind people see again too! That’s crazy. And awesome! Welcome to the 21st century! Here’s the sources:
Like the liver, heart, and brain, your outer most covering is an organ. An average man has enough skin on his body to cover approximately twenty square feet. For an average woman it is approximately seventeen square feet. Roughly 12% of your body weight is from your skin. Amazingly, your skin replaces 45,000+ cells in just a few seconds. It’s constantly growing new skin and shedding old skin.
Mine is also the brain. To me its fascinating how the body protects it when it comes into harm. There is so much still to find out about how it works and how to treat diseases that originate within it.
