In this deck, we'll explore the human digestive system. We'll follow the journey of food through the body and learn how our bodies break it down and absorb nutrients. We'll cover five key processes: ingestion, digestion, absorption, assimilation, and egestion.

The first process is ingestion. This is the scientific term for the act of taking substances, like food and drink, into the body through the mouth.

Next is digestion. This is the process where large, insoluble food molecules are broken down into small, water-soluble molecules that can be absorbed into the bloodstream.

After digestion, absorption occurs. This is the process where the small, soluble nutrient molecules move from your intestines into your blood or lymph.
