The small intestine (about 22 feet long in an adult) absorbs nutrients from chyme that comes from the stomach.
The small intestine has to be long so that it can fully absorb all of the nutrients in the chyme (digested food).
Chyme enters the small intestine from the stomach on the right side, known as the pyloric sphincter. Once in the small intestine, chyme is further broken down and nutrients are absorbed into the body.
In the small intestine, chyme is further broken down by enzymes and absorbed into the bloodstream for nutrients to be used by the body.
After leaving the stomach, food chyme enters the small intestine. The next stage of digestion for the chyme in the small intestine involves the absorption of nutrients into the bloodstream.
Chyme is the partially digested food mixture that passes from the stomach to the small intestine for further digestion and absorption of nutrients. From the small intestine, the remains of the chyme continue through the large intestine where water is absorbed and waste products are formed before being excreted from the body.
Food leaves the stomach and enters the small intestine through the pyloric sphincter, a muscular valve at the end of the stomach. This process is controlled to ensure that the small intestine can properly digest and absorb nutrients from the food.
small intestine helps absorb nutrients
The watery liquid that moves from the stomach to the small intestine is called chyme. Chyme is a mixture of partially digested food, stomach acid, and enzymes that is produced in the stomach to aid in digestion and absorption of nutrients in the small intestine.
The nutrients in the chyme would not be absorbed by the villi and your body would not get the nutrients.
it is adapted to absorbing nutrients due to the villi present in the small intestine.
The role of the villi in the small intestine is to absorb nutrients.
