Gastrointestinal tract
Tractus gastrointestinalis · Trávicí trubice
Digestive system
Looks like
A 7-metre muscular tube from gullet to anus, coiled in the abdomen, lined by a renewing surface.
What it does
Breaks food down, absorbs it, and moves the rest along.
Keeping it well
Fibre, water, regular meals, movement. Blood in the stool, or a lasting change in bowel habit, needs investigation.
