What does the digestive system primarily do?

• A. Regulates hormones in the body
• B. Breaks down food and includes a group of organs
• C. Delivers oxygen to tissues and removes carbon dioxide
• D. Controls the nervous system's responses

Answer: (B)

The digestive system primarily breaks down food and consists of a complex group of organs, including the mouth, esophagus, stomach, intestines, and accessory organs like the liver and pancreas. Its main function is to convert the food we eat into smaller molecules that can be absorbed into the bloodstream and utilized by the body. This process involves mechanical digestion, such as chewing and grinding food in the stomach, as well as chemical digestion, where enzymes break down carbohydrates, proteins, and fats into their basic building blocks. The overall goal is to extract nutrients necessary for energy, growth, and cell repair while also eliminating waste products from the body.
