INTESTINES Meaning and
Definition
-
Intestines are a crucial part of the human digestive system and are specifically responsible for the process of digestion and absorption of nutrients from food. They are a long, tubular organ that forms part of the alimentary canal. The intestines are divided into two sections: the small intestines and the large intestines.
The small intestines are further divided into three parts: the duodenum, jejunum, and ileum. They are responsible for the majority of nutrient absorption, where enzymes break down food into smaller molecules and nutrients are absorbed into the bloodstream.
The large intestines, on the other hand, include the cecum, colon, and rectum. The primary function of the large intestines is to absorb water and electrolytes from undigested food, consolidate waste materials, and eliminate them from the body in the form of feces.
Intestines are known for their intricate structure, with inner walls containing millions of tiny finger-like projections called villi that increase their surface area, facilitating greater absorption of nutrients. They are also home to various beneficial bacteria that aid in digestion and maintain a healthy gut flora.
Overall, intestines play a vital role in the digestion and absorption of nutrients, helping nourish the body while eliminating waste, making them an essential part of the digestive system.
