PATHOLOGY

Detailed explanation-1: -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-2: -Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin.

Detailed explanation-3: -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.
