Which system converts food into energy and essential nutrients?

• A. Excretory system
• B. Digestive system
• C. Nervous system
• D. Circulatory system

Answer: (B)

The digestive system is responsible for converting food into energy and essential nutrients. This system encompasses various organs, including the mouth, esophagus, stomach, intestines, and accessory organs such as the liver and pancreas. When food is consumed, the digestive system breaks it down into smaller, absorbable components. This process starts in the mouth with chewing and saliva, continues in the stomach where gastric juices further digest the food, and culminates in the small intestine where most nutrient absorption occurs. The nutrients absorbed into the bloodstream provide energy for bodily functions, growth, and repair. Understanding the specific role of the digestive system highlights its critical function in nourishment and energy production, which are essential for overall health and well-being. Other systems mentioned, such as the excretory, nervous, and circulatory systems, have distinct roles that do not include the direct conversion of food into energy.
