What is an intestinal obstruction (blocked intestine)?
You have a small intestine and a large intestine. The small intestine is a long coiled tube that connects your stomach to your large intestine. The large intestine is shorter but wider and leads from the end of the small intestine to the rectum. Your intestines receive food and liquids from your stomach. They digest and absorb most of this material. What's left over leaves the body as stool (poop) through the rectum and anus.
The small and large intestines each can become blocked.
