Understanding the Human Digestive System (Demo)

The human digestive system is a coordinated group of organs that work together to break down food, absorb nutrients, and eliminate waste. Beginning with the mouth and continuing through the oesophagus, stomach, intestines, and associated glands, this system transforms complex foods into simple molecules that cells can use for energy, growth, and repair. Understanding how each part of the digestive system contributes to this process reveals how the body obtains the resources it needs to function properly.
