The answer is very simple, it does not. Any particle that is small enough to diffuse through the cell membrane can, and will diffuse into the blood. That is why it is so important not to put things into your body that are not good for you. Your body will absorb them without knowing if it is bad or good.

Nutrients are absorbed into the bloodstream primarily in the small intestine.
Nutrients enter the body through the digestive system, primarily in the small intestine. They are absorbed into the bloodstream and transported to cells throughout the body to support overall health and well-being.
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.
The nutrients your body needs are mostly water and food
the nutrients your body needs are sugar, starch, and fiber.
bloodstream through the walls of the small intestine. Here, nutrients are absorbed into the bloodstream and transported to cells throughout the body where they are used for various metabolic functions. Any remaining waste is passed out of the body through the large intestine.
Before digested food can nourish your body, it must enter the bloodstream through the walls of the small intestine. Once the nutrients are absorbed into the bloodstream, they are transported to cells throughout the body, where they can be utilized for energy, growth, and repair. This process ensures that the body receives the essential vitamins, minerals, and macronutrients needed for optimal functioning.
The small intestine takes the nutrients from food and sends them wherever they are needed in the body.
After nutrients are digested in the small intestine, they are absorbed into the bloodstream through the walls of the small intestine. This process is facilitated by tiny blood vessels called capillaries and specialized cells that line the intestine, allowing the nutrients to be transported to different parts of the body for energy and growth.
The bloodstream is the roads, the railways, and the airports of the body. Everything that goes from one part of the body to another enters the bloodstream at some point.
The small intestine is the site of most chemical digestion and absorption in the digestive tract. During absorption, nutrients enter the bloodstream, and the circulatory system can then transport these nutrients to all body cells.
