The Vietnamese word "ruột chay" refers to a specific part of the small intestine called the jejunum in English. The jejunum is the middle section of the small intestine, located between the duodenum and the ileum. It plays an important role in digesting food and absorbing nutrients.
In medical or biological discussions, "ruột chay" can be used when talking about gastrointestinal health, surgeries related to the intestines, or digestive disorders.
While "ruột chay" specifically refers to the jejunum, it is important to note that "ruột" alone can refer to any part of the intestines, depending on the context.
