Liver recieves nutrients from the digestive tract using the hepatic portal vein system, which are further absorbed and supplied to the body.

Small intestines consist of micro hair-like structures, the villi and microvilli that aid in nutrients absorption by increasing the surface area.

Stomach is the only digestive organs with multiple layers of muscles that breaks down large pieces of food into smaller chunks.

Pancreas serves the function of secreting different enzymes (amylases, lactase, galactosidase) that can digest carbohydrates, lipids, and proteins depending on the source of food you have eaten at that given moment.

Large intestines houses some good bacteria, our normal micro flora that further breakdown and digest food that might have passed. These freindly bacteria also act as source of vitamin B and K.
