Which organ is involved in the digestion process by breaking down food and absorbing nutrients?

The small intestine plays a crucial role in the digestion process as it is primarily responsible for breaking down food and absorbing nutrients. After food leaves the stomach, it enters the small intestine, where enzymes from the pancreas and bile from the liver further digest it. The walls of the small intestine are lined with tiny finger-like projections called villi, which increase the surface area for absorption. As the partially digested food (chyme) moves through the small intestine, nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed into the bloodstream, providing essential nourishment to the body. This process is vital for maintaining health and energy, as the body relies on these absorbed nutrients for various functions.
