digestive systems
Food breakdown machinery
The digestive system is the group of organs that break down food into nutrients the body can absorb.
In humans, this includes the mouth, esophagus, stomach, intestines, and associated organs like the liver and pancreas.
Different animals have dramatically different digestive systems—ruminants have multiple stomach chambers, while birds use gizzards to grind food.
