There are 1108674 EST sequences in digestive system.

    The digestive system is a series of connected organs from mouth to
anus whose purpose is to break down, digest and excrete wastes from the
food we eat. The digestive system breaks down complex food molecules
into simple molecules, so that they can easily be absorbed into the
bloodstream. These molecules are transported in the blood to the body's
cells, where they are used for maintenance, growth and reproduction.
