Study Notes

Small Intestine:

Part of the digestive system, approximately 6 meters long.
Consists of three sections: duodenum, jejunum, and ileum.
Digests and absorbs nutrients from food.
Uses digestive enzymes and bile to break down carbohydrates, proteins, and fats.
Villi and microvilli increase surface area for efficient absorption.
Nutrients are absorbed into the bloodstream and used for energy, growth, and repair.
Contains specialized cells that defend against harmful bacteria and viruses.
Plays a vital role in the immune system.

Large Intestine:

Final segment of the digestive system.
Absorbs water and electrolytes from indigestible food matter.
Compacts waste into feces and eliminates it through the rectum and anus.
Divided into four parts: cecum, colon, rectum, and anus.
Colon is the longest segment and absorbs water, electrolytes, and vitamins.
Gut microbiota ferments remaining carbohydrates and fiber.
