biol+1+modelling+digestion+lesson

Your fabulous models of the mammalian digestive system are below. Remember it is important that you can identify where you were accurate as well as inaccurate. Fell free to write some comments about this below each image.

I think it's fair to say this one is clealy the best.anonymous If that's the case then perhaps you can say why. VM

Comments Comparing the three models with my current understanding of the digestive systems, all three groups were able to accurately display the human digestive system, to some degree. Each groups small and large intestine were different, in terms of what they looked like and where they started and finished, I think this was due to the fact that it is hard to read something and then turn it into a plasticine model.

A relevant comment Adam, but I am hoping that you and the others can also highlight apsects that were inaccurate in your models. VM

- The Oesophagus should not be curved in the MMR group - The Liver is to far away from the stomach in the JLA group - The Duodeum is in the wrong place in the DOLL group That was my little imput:) It's great you have highlighted these points but perhaps it would be even better if you could suggest actual corrections. I wouldn't say the liver is too far away, though you are right in implying it is in the wrong position. Where should it be?VM

The liver is too high, and the whole composition of the gut id portrayed too spread out. Also, the small intestine doesn't appear as long as it should be. APART FROM THAT group DOLL is definately the best looking. (Sorry voj for the many editing) by LB

Which liver are you talking about? Great point about the length of the small intestine compared to that of the large intestine LB and don't be sorry. I want you to be editing stuff as much as possible because that way you strengthen your understanding and ability to communicate biology accurately.VM

the liver of DOLL? LB
