The blood carries nutrients from the small intestine to all over the body. The villi in the small intestine allow nutrients from digested food to pass through the intestinal wall to the blood vessels. Then the blood carries the nutrients away.

Digestive System
The system in the body that absorbs nutrients is the digestive system. Within the digestive system is the small intestine. When food passes through the small intestine, villi, absorb all of the nutrients the body needs from the food. Villi are small fingerlike projections in the small intestine that increase surface area and "reach" out to the food and absorb its nutrients. So, to answer your question, villi that are in the small intestine within the digestive system absorb what nutrients our body needs.
It is part of the digestive system for the small and large intestines do their part in digesting all the food we eat. The small intestines takes the nutrients out of our food and puts it into our blood stream and the large intestines (colon) takes the moisture out of the digested food (bolus) for excretion.
The digestive system is supose to break down food and the small intesine obsorbs the nutrients and delivers the nutrients to the body

they don't have a digestive system o.o they simply absorb the nutrients from it's host
Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.

Nutrients from the digestive system enter the circulatory system. From there, they are transported to all body cells.
The digestive system does not have as one of its functions the need for nutrients, apart form them needed to keep it healthy and functioning. It is more appropriate to ask, what nutrients do the cells of the body need? And how can the digestive system function optimally in order to accomplish that goal? The purpose of the digestive system is to break down foods in order to supply nourishment to the cells of the body. So, ultimately, it is what we choose to ingest that will provide the nutrients that our body needs. The digestive system is just an avenue for good nutrition to be supplied to the body. So, to answer your question more technically: All nutrients are involved in the digestive system because that is how the nutrients gain access to all the cells in the body.
Tapeworms are parasitic; they don't have need a digestive system because they absorb the nutrients they need from their host(s).
Nutrients are found throughout the digestive system. Most nutrients are absorbed in the small intestine.
The digestive system separates the nutrients that your body needs from what it doesn't need, and then the not needed stuff becomes solid and liquid waste.
The circulatory system works with digestive system to circulate the nutrients to all the body parts. The nutrients are digested and absorbed by the digestive system. The circulatory system circulates the nutrients throughout the body.
