ANATOMY

Detailed explanation-1: -In fact, many small molecules are directly absorbed, and usually don’t need digestion; for example: Water (There are no enzymes to digest water). Simple sugars (mainly Glucose & Fructose). Minerals (like Sodium, Potassium, … etc.).

Detailed explanation-2: -These single sugars include glucose, galactose and fructose, and your small intestine absorbs them without needing to digest them first.

Detailed explanation-3: -Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

Detailed explanation-4: -What happens to the digested food molecules? The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
