organ pencernaan yang memiliki vinus adalah

The digestive organ that has villi is the small intestine. Villi are tiny, finger-like projections that increase the surface area of the small intestine, allowing for better absorption of nutrients from food. The small intestine is where most of the digestion and absorption of nutrients takes place. It is divided into three sections: the duodenum, the jejunum, and the ileum. Villi are found throughout the entire small intestine, but they are most numerous in the jejunum. The villi are covered in a layer of cells called enterocytes. These cells are responsible for absorbing nutrients from the digested food. The villi also contain a network of blood vessels and lymphatic vessels, which transport the absorbed nutrients to the rest of the body. The presence of villi greatly increases the surface area of the small intestine, which allows for efficient absorption of nutrients. It is estimated that the villi in the small intestine increase the surface area by up to 600 times. This large surface area is essential for the body to absorb the nutrients it needs from food. In addition to increasing surface area, the villi also play a role in the production of digestive enzymes and hormones. The enterocytes that line the villi produce enzymes that break down food molecules into smaller, absorbable units. The villi also produce hormones that regulate the digestive process. The villi are an important part of the digestive system and play a vital role in the absorption of nutrients. They are responsible for increasing the surface area of the small intestine, producing digestive enzymes and hormones, and transporting absorbed nutrients to the rest of the body.
