What system is responsible for breaking down food into absorbable forms?

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

Answer: (B)

The digestive system is the one responsible for breaking down food into absorbable forms. This complex system involves various organs, including the mouth, esophagus, stomach, small intestine, and large intestine, each playing a specific role in the digestion process. When food enters the mouth, it is mechanically broken down by chewing and mixed with saliva, which contains enzymes that begin the digestive process. As food travels down the esophagus, it reaches the stomach, where stomach acids and enzymes further break it down into a semi-liquid form known as chyme. This chyme then moves into the small intestine, where the majority of nutrient absorption occurs, aided by enzymes from the pancreas and bile from the liver. The absorbable forms of nutrients, including carbohydrates, proteins, and fats, are then absorbed through the walls of the small intestine into the bloodstream, allowing the body to utilize these elements for energy and cell function. Overall, the digestive system is essential for converting the food we consume into the energy and nutrients our bodies need to function effectively.
