Detailed explanation-1: -As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
Detailed explanation-2: -The passage of digested food from the digestive tract into the circulatory system is called absorption. Both chemical and mechanical digestion makes food particles small enough to be easily absorbed into the bloodstream. The absorption takes place in the small intestines.
Detailed explanation-3: -Figure 2: The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Some chemical digestion occurs in the mouth. Some absorption can occur in the mouth and stomach, for example, alcohol and aspirin.
Detailed explanation-4: -However, about 95 percent of nutrient molecules are absorbed in the small intestine. The absorption of the majority of these molecules takes place in the second part of the small intestine, called the jejunum.
