Final answer:
The absorption of nutrients across the digestive tract involves transport of digested material, lymph, water, vitamins, blood, electrolytes, and waste materials.
Step-by-step explanation:
After food is digested, the resulting nutrients are absorbed. Absorption is the process in which substances pass into the bloodstream or lymph system to circulate throughout the body. The absorption of nutrients occurs mainly in the small intestine. Any remaining matter from food that is not digested and absorbed passes out of the body through the anus in the process of elimination.
