through cells in the villi of the small intestine
The digestive system extracts nutrients from food and releases them into the bloodstream for transport to cells around the body. Nutrient absorption primarily takes place in the small intestine, where nutrients are absorbed through the intestinal wall and enter the bloodstream through tiny blood vessels called capillaries.
Nutrients exit and waste enters red blood cells in the capillaries within tissues. These exchanges occur through the thin walls of the capillaries by diffusion.
The circulatory system is responsible for the distribution of food nutrients to different parts of the body. After nutrients are absorbed in the digestive system, they enter the bloodstream, where the circulatory system transports them to cells and tissues. This system includes the heart, blood vessels, and blood, ensuring that essential nutrients reach their destinations efficiently.
villi in the esophagus help move nutrients into the blood
usually nutrients enter the blood vessels through the small intestines
Nutrients enter the blood primarily through the small intestine. After food is broken down in the stomach, nutrients are absorbed through the lining of the small intestine and into the bloodstream. From there, the blood carries these nutrients to different parts of the body where they are used for energy and growth.
Nutrients from food and beverage is absorbed inside the walls of the small intestine. As we digest our food, all nutrients are taken in the small intestine and would most probably then enter our bloodstream from there on.

through cells in the villi of the small intestine
the nutrients enter the blood in the small intestine. The lining of the small intestine is called the villi, that is were the blood is absorbed into the bloodstream
The place is the same for both; the alveoli in the lungs.
All nutrients we have taken are absorbed into the blood in the small intestine. The excess are stored in the liver from where if required is again absorbed into the blood.
