Verified step by step guidance1
Begin by understanding the stages of food processing: ingestion, digestion, absorption, and elimination.
Ingestion is the first stage, where food is taken into the body. It involves eating or consuming food.
Digestion follows ingestion and involves breaking down food into smaller molecules. This process includes mechanical and chemical digestion, where enzymes play a crucial role.
Absorption is the stage where the digested nutrients are absorbed into the bloodstream from the digestive tract.
Elimination is the final stage, where undigested materials are expelled from the body. This is not absorption, but rather the removal of waste.
