The Digestive System- the digestion of food begins in the mouth. What does it do?. The digestive system consists of several organs that work together to: ingest food Breakdown food into smaller molecules, so that the nutrients that can cross the cell membrane absorb nutrients
Digestive enzymes break down macromolecules into small organic molecules that can be absorbed by cells

This weight loss surgery is not for everyone! Here’s what’s involved:
The surgeon creates a small pouch at the top of your stomach and adds a bypass around a segment of the stomach and the small intestine. The surgeon staples the stomach at the top, sealing it off from the rest of the stomach.
The resulting pouch is about the size of a walnut and can hold only and ounce of food,.
Then the surgeon cuts part of the small intestine and sews part of it to the pouch. Food enters the small intestine directly, limiting your ability to absorb calories
