Digestive System

DESCRIPTION

The digestive system plays a crucial role in breaking down food into nutrient molecules that our bodies can absorb. The process begins in the mouth where food is chewed and mixed with saliva for easier swallowing. It travels through the esophagus to the stomach, where it is stored and broken down further. Nutrients are extracted in the small intestines, while waste is prepared for elimination in the large intestines. The anus regulates the excretion of solid waste, completing the digestive journey. This overview highlights the importance of each digestive organ.
