villi
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
Food molecules are primarily absorbed into the bloodstream in the small intestine. The inner lining of the small intestine is covered in finger-like projections called villi, which increase the surface area available for absorption. Nutrients from food pass through the walls of the small intestine and into the bloodstream, where they are transported to cells throughout the body.
Glucose is absorbed into the bloodstream through a process called facilitated diffusion in the small intestine. Specialized proteins called glucose transporters help move glucose molecules from the intestine into the bloodstream, where it can be used for energy by the body's cells.
In the intestine, complex molecules are broken down into simpler molecules by enzymes released from the pancreas and small intestine. These simpler molecules, such as sugars, amino acids, and fatty acids, can then be absorbed into the bloodstream through the intestinal lining for use by the body. The process of breaking down molecules in the intestine is crucial for extracting nutrients from food.
Water is absorbed into the blood through a process called osmosis in the small intestine. The water molecules pass through the walls of the small intestine and into the bloodstream, where they are then circulated throughout the body.
Nutrients are absorbed into the bloodstream through the lining of the small intestine. This process involves breaking down food into smaller molecules, which are then transported across the intestinal wall and into the bloodstream for distribution to the rest of the body.
Through the villi in the small intestine
Through the bloodstream
Assimilation of food molecules into the blood takes place in the small intestine. The small intestine is lined with villi and microvilli, which increase the surface area for absorption. Nutrients are absorbed through the walls of the small intestine and then enter the bloodstream to be distributed to cells throughout the body.
Alcohol enters the bloodstream through absorption in the stomach and small intestine. It is then carried through the bloodstream to the brain and other organs, where it can have various effects on the body.
Glucose enters the small intestine through the process of digestion. When carbohydrates are broken down in the mouth and small intestine, glucose molecules are released and absorbed through the wall of the small intestine into the bloodstream.
