As food travels through the digestive system,__________.

Question

Quizplus · Accepted Answer

As food travels through the digestive system, macromolecules such as proteins, carbohydrates, and lipids are broken down into their subunits (A). Nutrients such as vitamins, minerals, and amino acids are absorbed into the bloodstream (B), and waste products such as undigested food and bacteria are eliminated as feces (D). Therefore, choice E, which includes options A, B, and D, is the most complete and accurate answer. Choice C, which states that nutrients are delivered to body tissues, is not entirely correct as nutrients are first absorbed into the bloodstream before being transported to body tissues.
