Mouth
A muscular tube that connects the mouth to the stomach. It transports food via peristalsis (wave-like muscle contractions).

Absorbs remaining nutrients and passes waste to the large intestine.
Ileum
A small pouch at the beginning of the large intestine.

Cecum
Hosts beneficial bacteria that aid in fiber fermentation.
Large intestine
Absorbs water and electrolytes from digested food.
Large Intestine
Further ferments remaining carbohydrates and fiber.
