Lengths of intestines

  • Lengths of first 3 parts of the digestive system after the stomach i.e. Duodenum, Jejunum and Ileum: 

To remember the lengths , remember the story of a tiger, which ate a dozen doctors who had gone to the forest for a picnic, including the famous Doctor Indiana Jones. News reported in Radio: One (tiger) Ate 12 (1-8-12) , including Dr. Indiana Jones referring to 1, 8 and 12 feets, which are the respective  lengths of Duodenum, Ileum and Jejunum.

  • Lengths of 4 parts of Duodenum ( Remember : 1-2-3-4 = 2-3-4-1 ) :

1st part = 2 inches

2nd part = 3"

3rd part = 4"

4th part = 1"

the first mnemonic says that duodenum is 30cm i.e 12 inches
and the second tells it is 25cm i.e 10 inches

the second is correct i know... the first can confuse us.

and i just missed to see that the info is not correct

Jejunum is smaller than ileum

it should be 8 feet jejunum and 12 feet ileum..

actually jejunum is 3-6 feet and ileum is 6-12 feet.
