The process of digestion and absorption allows the human body to convert food into energy, building blocks, and essential nutrients. Every meal, no matter how complex, undergoes a series of transformations that break it down into simple molecules.
These molecules are then transported as nutrients to blood and lymph, ensuring that every cell receives what it needs to function. Understanding how this system works highlights the importance of mechanical breakdown, digestive enzymes, and the specialized structures within the digestive tract.
