Which section of the digestive system is responsible for receiving chyme and further digesting it?
The large intestine
The duodenum
The jejunum
The gallbladder
Correct Answer : B
The duodenum is the first section of the small intestine. It receives partially digested food (also called chyme) from the stomach, further digesting it with the help of enzymes released by the gall bladder. Then, the food enters into the jejunum, then the ileum. The large Intestine's main function is the reabsorption of water into the body to form solid waste. It also allows for the absorption of vitamin K produced by microbes living inside the large intestine.

Phase changes such as evaporation and sublimation are physical changes. Changing the ratio of ingredients in a mixture, like adding more water to clay, does not change it chemically, but it can change some of the mixture's physical properties.
