My teacher added an extra question to my frog disection lab (lucky us..) but i've honestly looked everywhere and can't find an answer to the following question:
"Compare the relative lengths of the stomach, small intestine, and large intestine in a frog to that of a human. Explain any differences."
Any help will be appreciated =)

When the question asks about relative lengths, it means to comapare the length of the human's stomach to the human's small intestine and to the human's large intestine. This web site says that the small intestine of a human is 6 m long while the large intestine is 1.5 m long. (http://hypertextbook.com/facts/2001/AnneMarieThomasino.shtml)
This site says that the human stomach is about 0.3 m long. (http://www.encyclopedia.com/doc/1E1-stomach.html)
Human -- 0.3m stomach: 6m small intestine: 1.5m large intestine.
This shows us that the small intestine of a human is about 4 times as long as the large intestine and is about 20 times as long as the stomach.
Did you measure these organs in the frog dissection? Compare the lengths of the frog's organs like my example of the comparison of the lengths of the human's organs. What do you notice?

I've dissected a frog in my day and I think that the frog has an especially large stomach for an animal of its size. Why? To hold the large bugs that is just swallows down. They have tiny teeth and don't chew. The other parts are pretty proportional, I think.
