Final answer:

Digestion is considered complete when the nutrients from digested food are absorbed into the bloodstream, mainly through the small intestine.

Step-by-step explanation:

Digestion is considered complete when the food is broken down into smaller molecules, and these nutrients are absorbed into the body, particularly when they enter the bloodstream via the small intestine. The correct answer to when digestion is considered complete is when the nutrients are delivered to the liver and released into the bloodstream, which occurs after absorption in the small intestine. This is because the digestive system's primary functions include not only the digestion of food but also the absorption of nutrients and the elimination of solid waste. Absorption enables nutrient molecules to circulate throughout the body and be utilized by cells. Remaining matter that cannot be digested or absorbed is compacted into feces in the large intestine and is expelled from the body, which is a separate process from the completion of digestion.
