What is the primary purpose of the digestive system?

• A. To filter blood
• B. To break down food and absorb nutrients
• C. To transport oxygen
• D. To regulate hormones

Answer: (B)

The primary purpose of the digestive system is to break down food and absorb nutrients. This intricate system facilitates the transformation of ingested food into smaller molecules that can be utilized by the body for energy, growth, and cellular repair. The digestive process involves various organs, including the mouth, stomach, intestines, and accessory organs such as the liver and pancreas, each contributing to the mechanical and chemical breakdown of food. As food is digested, essential nutrients such as carbohydrates, proteins, vitamins, and minerals are absorbed into the bloodstream through the walls of the intestines. This enables the body to obtain the necessary elements to function correctly. Without this essential process, the body would be unable to gain the energy and nutrients needed to support all its vital functions, highlighting the digestive system's critical role in overall health and well-being.
