Abstract

In Octopus, the caecum, the pancreas and the liver are involved in the absorption of 3H-glycine-labelled food. The caecum exhibits the highest specific activity while the liver absorbs the largest proportion of labelled material. The administration of stained food shows in vivo alternating phases of absorption and secretion in the liver and continuous absorption in the caecum.
