What is the task of digesting system?

The task of the digestive system is to break down food into smaller components that can be absorbed into the bloodstream. This process begins in the mouth, where saliva breaks down carbohydrates, and continues in the stomach, where stomach acid and enzymes further break down food. The food then passes into the small intestine, where it is further broken down by enzymes from the pancreas and bile from the liver. The nutrients from the food are then absorbed into the bloodstream through the walls of the small intestine. Any remaining waste products are passed into the large intestine, where they are eventually eliminated from the body.

In summary, the main tasks of the digestive system are:

- Mechanical breakdown of food into smaller pieces

- Chemical breakdown of food into nutrients that can be absorbed

- Absorption of nutrients into the bloodstream

- Elimination of waste products from the body
