Annette Morales · Accepted Answer

Final Answer : A, Explanation :  The digestive system's purpose is to break down food into small enough molecules that can be absorbed by the body and used as energy, building blocks, or other necessary functions. Absorption is the process by which these small molecules are taken up into the internal environment, such as the bloodstream, so that they can be transported to cells and tissues throughout the body. Excretion is the process of eliminating waste products from the body, which occurs after the nutrients have been absorbed. Denaturation is a process by which proteins lose their shape and function due to changes in their environment, such as changes in temperature or pH. Emulsification is a process by which fats are broken down into smaller droplets to aid in their digestion, but this is not the final step in absorption. Ingestion is the process of taking in food or drink through the mouth, but it does not explain what happens to the food after it is ingested.
