What is the meaning of blind tubule or blind end of tubule?
Dear student.
The hepatic ceaca are called blind tubules because they are blind at the free ends.
The junction of mid gut and hindgut (part of alimentary canal) of crustaceans such as cockroach bears 7-8 blind tubes called hepatic caeca that are present at its anterior end. They are lined by glandular cells which secrete various digestive enzymes like peptidases, trypsin etc. So these caeca helps in digestion of proteins, starch, fats etc.
