intesztin

intesztin is a term that refers to the intestines, which are part of the digestive system in vertebrates. The intestines are a long, tubular organ responsible for absorbing nutrients from food and eliminating waste. They are typically divided into two main sections: the small intestine and the large intestine. The small intestine is the primary site for digestion and absorption of carbohydrates, proteins, and fats. It is characterized by its long length and folded inner surface, which increases its surface area for absorption. The large intestine, in contrast, is shorter and wider. Its main functions include absorbing water and electrolytes from the remaining indigestible food matter and forming feces. Bacteria residing in the large intestine also play a role in breaking down certain substances and producing vitamins. The coordinated muscular contractions of the intestines, known as peristalsis, move food through the digestive tract. Disruptions to normal intestinal function can lead to various digestive disorders.
