Detailed explanation-1: -Chyme passes from the stomach into the duodenum. There it mixes with bile and pancreatic juices that further break down nutrients. Finger-like projections called villi line the interior wall of the small intestine and absorb most of the nutrients.

Detailed explanation-2: -The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins.

Detailed explanation-3: -After chyme is produced in the stomach, it is sent to the small intestine where most of the nutrients are absorbed. Next, it moves to the large intestine where water is absorbed and chyme becomes more concentrated. Eventually, chyme is processed into feces and is expelled through the rectum and anus.

Detailed explanation-4: -A small muscular valve called the pylorus (pie-LOR-is) controls when chyme is released into the small intestine. The small intestine: The small intestine is where many nutrients (like protein, carbohydrates, and fats) get absorbed into the bloodstream.

Detailed explanation-5: -Chyme is part liquid and part solid: a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and small intestine during digestion. Chyme also contains cells from the mouth and esophagus that slough off from the mechanical action of chewing and swallowing.
