The intestines are essential components of the gastrointestinal tract within our digestive system. Their primary roles are to break down food and allow the absorbed nutrients to enter the bloodstream. The intestines are divided into two main sections: the small intestine and the large intestine. Although the small intestine has a narrower diameter, it is significantly longer and more substantial than the large intestine. Together, these organs occupy most of the abdominal cavity, with their extensive length tightly folded to fit within the limited space.
