Where does the nutrients go when it leaves small intestine?

After leaving the small intestine, nutrients take different paths depending on their type:

1. Carbohydrates: Digested carbohydrates are broken down into simple sugars, primarily glucose, which is absorbed into the bloodstream through the walls of the small intestine. Glucose is then transported to cells throughout the body to be used as an immediate energy source or stored as glycogen in the liver and muscles for later use.

2. Proteins: Digested proteins are broken down into amino acids, which are absorbed into the bloodstream through the walls of the small intestine. Amino acids are the building blocks of proteins and can be used to synthesize new proteins or used as an energy source when carbohydrates are not available.

3. Fats: Digested fats are broken down into fatty acids and glycerol. Fatty acids are absorbed into the lymphatic system, a network of vessels that collects and transports fatty substances. The lymphatic system carries the fatty acids to the bloodstream, where they can be used for energy or stored as fat cells for later use.

4. Vitamins and Minerals: Vitamins and minerals are absorbed along the entire length of the small intestine. Water-soluble vitamins (such as vitamin C and B vitamins) and minerals (such as iron and calcium) are absorbed directly into the bloodstream. Fat-soluble vitamins (such as vitamins A, D, E, and K) are absorbed along with dietary fats and transported to the liver before being distributed to the rest of the body.

Once absorbed into the bloodstream or lymphatic system, nutrients are transported to various tissues and organs throughout the body, where they are utilized for various metabolic processes.
