through cells in the villi of the small intestine
The answer is small intestine.
Columnar epithelial cells.
Capillaries in the small intestine absorb nutrients from the digestive tract. Capillaries in the small intestine also bring oxygen and carry away waste from the intestine.

Through your small intestine
The duodenum (the first part of the small intestine).
The small intestine- micro-villi specifically in the small intestine. The micro-villi increases the surface area of the small intestine. which allows more food particles to enter the cells of the small intestine to digest.
Oxygen and particles of digested food get into the cells from the small intestine, from there they drain into the hepatic portal vein. The hepatic portal vein goes to the liver to filter out nutrients required and excesses are metabolized and converted.
Glucose is absorbed from the food you eat in the small intestine, while oxygen is inhaled into the lungs and then transferred into the bloodstream. Both glucose and oxygen are then transported by the circulatory system to cells throughout the body for energy production.
The small intestine is primarily made up of epithelial cells, which line the inner surface and are responsible for nutrient absorption. Other cells found in the small intestine include goblet cells that secrete mucus, enteroendocrine cells that produce hormones, and immune cells like lymphocytes that help protect against pathogens.
