Nutrients are absorbed in the intestines.
The stomach and the small intestine are the most important part for digestion. You CAN NOT live without a small intestine, since most nutrients are also absorbed from there also.
The appendix is anatomically part of the digestion system but its' function is part of the immune system.
Ileum is the last part (division) of small intestine. It absorbs all the remaining food that was not absorbed by jejunum. It contains microscopic villi that are responsible for assimilation of food.
Most of the nutrients in food are taken into the bloodstream by the second part of the small intestine, known as the jejenum. Whatever is leftover is absorbed into the large intestine before excretion.
digestion and waste disposal
I think you mean pancrease. It is part of the endocrine system. It secretes insulin and other hormones into the blood. It also aids in digestion by excreting fluid into the small intestine that aids in nutrient absorption.
micro villi in the jujeum (second part of your small intestine)
Food goes into the digestive tract (Gastro- intestinal passage), In the stomach and in the upper part of the small intestine the digestion is mostly complete. From there it is absorbed into the blood through the lining of the intestines. Thus the food is absorbed into the body and is distributed throughout the body.
This is part of the process of digestion.
i say its your back.
digestion and waste disposal
In worms, the process of digestion primarily occurs in the crop and gizzard, which are part of the digestive system. The crop temporarily stores food, while the gizzard grinds it down, aided by ingested soil particles. Following this, digestion continues in the intestine, where nutrients are absorbed into the bloodstream. This efficient system allows worms to break down organic matter and extract essential nutrients.
