El increíble viaje de los alimentos

The video explains the journey of food through the human digestive system, starting from the mouth where food is chewed and mixed with enzymes in saliva. It then travels down the esophagus to the stomach, where further digestion occurs with the help of enzymes and acids. Nutrients are released and absorbed in the intestines, while undigested food is expelled from the body. This process is essential for maintaining a healthy and active life.
